The Navy's mission is to maintain the freedom of the open seas. To that end the Navy employs and maintains air, land and ocean going vehicles and personnel necessary to accomplish this mission. The topics on the following pages provide a portion of the problems encountered by the Navy in order to fulfill its mission.
The Navy has identified 77 technical topics in this DOD Solicitation to which small R&D businesses may respond. This is in addition to the 290 topics identified in DOD SBIR Solicitation 91.1 which closed 11 January 1991. A brief description of each topic is included along with the address of each originating office. In addition, there are index and topic title sections which are provided for quick reference. This information is contained on the ensuing pages.
SBIR proposals shall not be submitted to the above address and must be received by the cognizant activities listed on the following pages in order to be considered during the selection process.
Selection of proposals for funding is based upon technical merit and the evaluation criteria contained in this solicitation document. Because funding is limited the Navy reserves the right to limit the amount of awards funded under any topic and only those proposals considered to be of superior quality will be funded. This year the Navy's SBIR budget was reduced by 25%. While this will not impact funds of Phase awards that result from the topics listed in this solicitation, it makes it extremely important that Phase award recipients influence the end uses of the technology since Phase II SBIR funds will be limited and thus highly competitive.
A new participant in the Navy's SBIR Program is the OFFICE OF ADVANCED TECHNOLOGY (OAT). They are responsible for identifying R&D projects, programs or Systems which meet critical fleet needs that can be taken to the full demonstration phase. As you read through the topic descriptions you will notice topics that are asterisked after the title. Those topics have been identified by OAT as having the potential to be full demonstration projects.

FY 1991 TOPIC DESCRIPTIONS



OFFICE OF NAVAL RESEARCH

N91-291 TITLE: Nonlinear Dynamics for Signal Processing


CATEGORY: Research
OBJECTIVE: To employ novel concepts from nonlinear dynamics and fractals to develop new techniques for signal processing and forecasting.
DESCRIPTION: Recent advances in nonlinear dynamics have broadened our appreciation of complex signals by relating chaotic signals to dynamical processes. Ideas of deterministic noise, fractal dimensions, and strange attractors can be useful in detecting complex signals in noisy backgrounds. One may or may not know the signal being sought or one may be trying to forecast natural phenomena. A range of techniques involving embedding dimensions, attractor smoothing, wavelet transforms, stochastic resonance, noise squeezing, periodicity functions, multi-fractals, invariant characterizations, Lyapunov exponents, etc., may be of use. Automated techniques for signal processing which take advantage of modern advances in dynamical systems and fractals are of interest.
Phase I is to identify issues and qualify concepts to demonstrate the viability of novel nonlinear dynamic methods for signal processing.
Phase II would produce devices/software capable of implementing the Phase I concepts.

N91-292 TITLE: High Temperature Transistors (HTT)


CATEGORY: Research
OBJECTIVE: To investigate semiconductors and develop transistor designs for high temperature applications.
DESCRIPTION: Nuclear reactors and turbine engines operated by the Navy could be operated more efficiently if onboard active sensor technology were available. While sensors capable of operating at 325 Celsius are available, the accompanying active electronic devices are not readily available. These devices require a semiconductor having a bandgap of 2.2 electron volts or higher and a compatible metallization technology.
During the Phase I program, a candidate semiconductor capable of sustained 325 Celsius operation will be demonstrated and a transistor design completed.
During the Phase II effort, the transistor would be demonstrated and an operational amplifier would be designed and tested to operate at 325 Celsius and with supply voltages between 5 and 24 volts.

N91-293 TITLE: 4-Dimensional Oceanographic Instrumentation


CATEGORY: Research
OBJECTIVE: To develop innovative instrumentation to measure oceanographic/meteorologic parameters.
DESCRIPTION: Innovative sensors/projectors and measurement techniques are solicited to obtain marine atmospheric, oceanographic (acoustical, optical, physical, biological, chemical, and geophysical) variables in 3D space and time. The emphasis is on (1) novel approaches and concepts for measuring multiple parameters coherently in 4D; (2) new methods of measuring fluxes, acoustic wavefields, or fluid motion of mixtures (i.e. water/bubbles/sediments/biological). Instruments can be towed/tethered sensors/projectors, elements in arrays, or suites of instruments on ROVs (remotely operated vehicles) to cite a few examples. Low cost, reliable, and/or expendable sensors/projectors and components (e.g. broadband, large dynamic range, high efficiency, compact, low power consumption projector/receivers) are particularly desirable. Full depth capability is desired in instrumentation planned for sub-surface use.
The Phase I proposal should provide a description of exactly what will be measured and to what accuracies and coherence as well as providing the design concept for achieving the measurements. Phase I should produce a proof of concept by demonstrating untested concepts or instruments.
Phase II would develop hardware and demonstrate feasibility in the laboratory. Field testing should be addressed via coordination with ongoing ONR field efforts. Potential approaches to industrial development that transitions program output should also be outlined.

N91-294 TITLE: Remote Environmental Data Link


CATEGORY: Research
OBJECTIVE: To provide user instrumentation for a broadband environmental data retrieval system.
DESCRIPTION: There is a growing need for remote environmental data retrieval systems that link data from surface/sub-surface oceanographic/acoustic sensors at sea to retrieval stations. Plans by Motorola indicate that a large number of broadband satellites could be placed in orbit in the near future that will create a network that can be tapped with cellular telephone technology. Other concepts such as acoustic telemetry, ground wave RF, meteor burst, and error corrected AM offer opportunities for data retrieval.
The Phase I program will design prototype field instrumentation with capabilities for multi-channel temporal storage, data transmission, and reception of instrument command functions to ensure that remote environmental/acoustic sensors can communicate to shore stations. Systems and/or components that are crucial to any/all network approaches can be propose Design considerations should emphasize low power consumption and costs. Data message sizes of 100 K Bytes including glob positioning and data error flagging and correction are desired. Transmission rates from sensors should be explicitly defined with desired rates sufficient to accommodate acoustic array data.
Phase II would initiate the plan by developing the transmitter/receiver, global positioning module if appropriate and temporary storage instrumentation. The probability of Phase II support will be strongly influenced by Phase I findings an external additional support from agencies willing to cooperatively fund early deployment of such instrumentation.

N91-295 TITLE: Identification of Microbially Influenced Corrosion


CATEGORY: Research
OBJECTIVE: To develop identifiers and identifying concepts for microbially influenced corrosion.
DESCRIPTION: Microbially influenced corrosion (MIC) has been recognized for more than 50 years but has frequently been ignored as a significant contribution to the degradation of structural materials. More recently the unexpected corrosion failure corrosion-resistant materials in relatively benign environments have re-emphasized the importance of MIC, and there is a need be able to identify MIC by simple and quick procedures. The correct diagnosis is particularly important in situations where preventive treatments for MIC, such as oxidizer additions, are expensive in terms of time, materials, equipment and environmental impact. Presently used techniques for the identification of MIC often rely on the general appearance of the corroded region such as shape of deposits and penetration, characteristic colors and location of attack. These may be followed by sampling, by specialized techniques, of the corroded material and of bulk fluids and by chemical, metallurgical and microbiological analysis. Less time-consuming and less expensive identifying techniques for MIC are much needed by failure analysts.
During the Phase I program, research will address identifying concepts for MIC which are capable of being developed into rapid diagnostic procedures.
During the Phase II effort, the Phase I concept would be further developed and verified in service environments and a diagnostic procedure for the quick identification of MIC will be made available. This diagnostic procedure may be developed as a test kit and/or service.

N91-296 TITLE: Concurrent Design System for Manufacturing


CATEGORY: Research
OBJECTIVE: To develop an integrated system for the rapid design and fabrication of custom parts for use in hydrodynamic: experiments.
DESCRIPTION: There is a need for the flexible, rapid and reliable production of physical part prototypes for hydrodynamic experiments. With recent advances in computing technologies, computing theories and manufacturing technologies, it may be feasible to develop an integrated concurrent product/process design system satisfying this need in specific domains. Manufacturing technologies such as stereolithography, selective sintering, plasma coating and others may have the potential for the rapid fabrication of part models. The size of these model parts is less than 0.3 meters in linear dimension. Computing technologies such as artificial intelligence, computational geometry, robust geometric modelers, an others are emerging important components of design systems. It is envisioned that an engineering design system built from these engineering will have the capability for synthesis and extensive analysis of product and process designs, for the graphical depiction of the product and process, for the real-time monitoring and controlling of the part production, and the creation of a physical part.
The objective of the Phase I effort is to specify an engineering product/process design system that facilitates the rigorous analysis and formal development from conceptual design through to physical model. The specification should describe: an open-system architecture using a client/server (or object-oriented) model; the human-computer interface and how this interface facilitates product and process design; and the underlying fabrication technology. A description of the operation of the system should be provided. Designs building upon ONR sponsored research in engineering sciences are encouraged.
The objective for the Phase II effort would be the development of an experimental research prototype based surface on the Phase I design.

N91-297 TITLE: Condition Based Machinery Maintenance


CATEGORY: Research
OBJECTIVE: To develop methods of detecting small, but permanent, changes in the condition of mechanical systems for the purpose of scheduling preventive maintenance.
DESCRIPTION: Recent developments in signal processing (e.g. wavelets) and the use of new classifiers such as Artificial Neural Networks (ANN) have shown promise for real-time pattern recognition. The vibrational response of machinery changes with the onset and propagation of a component fault. Substantial cost savings can be realized by detection and classification of this and abnormality prior to catastrophic failure. This effort will focus on mechanical systems such as gearboxes and bearings in noisy environments as found on ships and helicopters.
During Phase I, research will address the development or identification of signal preprocessing appropriate for 1 filtering diagnostic signal parameters and feature extraction for classification. A rational approach to choice and demonstration of preprocessors combined with suitable classifiers and learning algorithms is desirable. Use of real gearbox or bearing data is preferred, and will be provided by ONR if requested, although use of synthesized data may be acceptable. (This data is not required for proposal submission).
During Phase II, the Phase I system concepts would be further defined and implemented in hardware. In Phase II, a demonstration must be given of the chosen analysis method(s) as applied to a Navy data set and the correlation of the inferred condition with the true state of the mechanical system over its duty cycle.

N91-298 TITLE: Adaptively Compensated Hydrophones
CATEGORY: Exploratory Development is.
OBJECTIVE: A miniature piezoelectric hydrophone used in broad bandwidth applications can suffer from a loss in sensitivity due to loading by cabling between the hydrophone and its first preamplifier. A method is needed to minimize this loading effect while maintaining both broad bandwidth and an acceptable level of signal to noise performance.
DESCRIPTION: The Phase I effort should quantify the bandwidth and noise limitations of typical hydrophones both in production and in advanced development. The proposed method to alleviate the problem should be detailed and modeled to ascertain its ability to correct the problem. A sensitivity/tolerance study should be an integral part of the investigation to determine if the method can be reduced to practice. A breadboard circuit should be delivered along with a final report.
The Phase II effort should culminate with the final design and fabrication of a device which could be added to a typical hydrophone for the purpose of increasing its useful bandwidth without reducing the noise performance of the hydrophone. A small quantity of devices would be fabricated and tests undertaken to confirm the predicted performance. The final report would include a complete analysis of the receive subsystem of hydrophone, compensating device, and preamplifier.

N91-299 TITLE: Anti-Reflection Coatings for Use on Ultrahard Conformal Infrared Windows


CATEGORY: Exploratory Development
OBJECTIVE: The aim of this program is to develop materials and deposition processes to fabricate optical thin films to provide anti-reflection (AR) coatings of ultrahard conformal domes with sapphire, spinel or poly-crystalline diamond films for severe high temperature, oxygen-containing environments.
DESCRIPTION: The durability and extremely high thermal shock resistance of sapphire, spinel and poly-crystalline diamond offer a means to protect IR window and dome materials from erosion and environmental attack while improving optical performance, thermal shock resistance and lifetime. Optical quality coatings that can be deposited and adhere to diamond must be developed to provide useful AR coatings that can survive extreme environments. The AR coating should be optimized for transmission in the 8-12 um region. Ideally, it should retain good transmission from the ultraviolet to millimeter wavelengths. A secondary function of the AR coating is to protect the diamond from oxidation by the atmosphere at temperatures up to 10000C. Optical- quality finishes of about 25A RMS roughness or better will be needed for coated flat and curved surfaces up to 2 inches in diameter. Present diamond abrasive methods are slow, expensive and result in substrate subsurface damage which may limit optical and rain erosion performance. Deposition techniques supplying dense, uniform films will be needed. An emphasis will be placed on scaleable processes. Reflectance and transmittance will be used for optical property measurement. Mechanical properties such as stress, adhesion and thickness uniformity using optical microscopy and scattered light analysis of the films will be determined.
Phases I and II should also address the effects of chemical/mechanical or ion beam finishing techniques on performance and dome cost.

N91-300 TITLE: Reverse Engineering of Assembly Code


CATEGORY: Exploratory Development
OBJECTIVE: To develop an automated approach for the reverse engineering of assembly code.
DESCRIPTION: When the aggregate, integrated, real-time functions of a Navy battle group -carrier, surface combatant ships, aircraft -are modeled, it becomes clear that the U. S. Navy develops and deploys some of the world's largest, most complex information processing systems. The software that battle group operations depend on consists of millions of lines of source code. Many programs are written in computer languages (such as dialects of CMS-2) which support embedded assembly code. During the system life cycle, many software maintenance changes are made. These changes are rarely reflected in the supporting system documentation. This leads to the state where the only true representation of the existing system is the current source code implementation. Reverse engineering provides support for the standard systems engineering process by providing a means for extracting as much high level information as possible to be represented in a detailed design. This high level design information is needed in order to improve maintenance, reduce costs, encourage reuse, and aid in the transition of older systems to new Ada implementations. This research will develop a strategy for automating the reverse engineering process of assembly code. This methodology should integrate to existing development and maintenance environments and automated support tools such as CASE t' products.
Phase I work should show the feasibility of reverse engineering assembly code for existing systems that are very large and have real-time characteristics. The proposed strategy should be documented in an initial report. The requirements and design for a tool to automate this strategy should be available at the end of Phase I.
Phase II work should include the complete development of the automated tool. A test case providing proof-of-concept for the strategy and tool should be completed and documented.

N91-301 TITLE: Design Technique for Automatic Generation of Support Documentation for Large Real-Time Systems


CATEGORY: Exploratory Development
OBJECTIVE: To develop an automated approach for generating documentation (i.e., user's guides, specifications and reports) which provides high level textual representations of systems.
DESCRIPTION: When the aggregate, integrated, real-time information processing requirements of a Navy battle group -carrier, surface combatant ships, and aircraft -are modeled, it becomes clear that the U. S. Navy develops and deploys some of the world's largest, most complex information processing systems. The development of these systems generally takes several years, requiring the large development teams working together to fulfill the system requirements. Massive documents describing the functionality of the system support the system once it is deployed. These documents are often written early in the development process and can be inconsistent and incomplete with respect to the actual system implementation. Modifications made to these systems after delivery are often not reflected in the supporting documentation. Some commercial products which generate documentation are available for small or mid-size systems. They cannot handle the large-scale systems used by Navy.
This research will develop a strategy for generating support documentation such as user’s guides, specifications, and other reports describing the functionality, behavior, and data structure of systems. The proposed strategy should be automatable in order to minimize the time and manpower required to perform the documentation generation. The tool should integrate with existing development and maintenance environments and automated support tools such as CASE products.
Phase I work should show the feasibility of generating documentation for existing systems that are very large and have real-time characteristics. The proposed strategy should be documented in an initial report. The requirements and design for a tool to automate this strategy should be available at the end of Phase I.
Phase II work should include the complete development of the automated tool. A test case providing proof- of -concept for the strategy and tool should be completed and documented using a typical Navy system which will facilitate the transition into the maintenance environment of the Navy.

N91-302 TITLE: Methodology and Tools for Improving the Navy Acquisition Process


CATEGORY: Exploratory Development
OBJECTIVE: To develop methodologies/tools which facilitate the Navy's planning process for acquiring developmental systems.
DESCRIPTION: Various computerized tools have been developed to support the management of technology development and systems acquisition programs, including PERT/Gantt charts and other project schedule/resource management programs and the "what-it" capabilities of spreadsheet programs. A major need exists, however, for additional methodologies and tools to help the Navy plan, evaluate and select Development and Acquisition programs.
Phase I should develop concepts for candidate methodologies and tools, and provide a strong rationale for both (a) the feasibility of implementation of the proposed concepts and (b) the utility of the final product in increasing the effectiveness and efficiency of the Navy's acquisition process.
Phase II would see the refinement of the concepts developed in Phase I and the development/delivery of prototype tools.

OFFICE OF ADVANCED TECHNOLOGY
N91-303 TITLE: Advanced Systems and Technologies for Future Naval Warfare *
CATEGORY: Advanced Development I
OBJECTIVE: Enhance Navy's future warfare capabilities in ASW, AAW, STK/ASUW, MIW, AMW, C3I, EW, Space, Special Warfare, Manpower/Personnel/Training, Medical, Strategic Offense/Defense, Logistics, and Coordinated Battle Force Operations.
DESCRIPTION: Navy is seeking new, innovative, high risk/payoff ideas in technologies and/or advanced systems concepts that support the Navy's mission in the years 2000 and beyond.
Phase I: Proposal should address: a) the system concept or technology being proposed, b) the expected operational utility in future naval warfare, c) description of critical subsystems/technologies, d) required subsystem/technology performance, e) current subsystem/technology maturity, f) the scientific principals involved (show quantitative formulation where appropriate), and g) the work planned to demonstrate technical feasibility and transition of the system into the Navy's acquisition system.
Phase II: Development of the system concept/demonstration of critical components to reduce the acknowledged risk to acceptable levels and transition the proposed system into the fleet at the earliest time.
