DEVELOPMENT OF AN IMPROVED MODEL FOR ACOUSTIC SCATTERING FROM A TURBULENT MEDIUM IS PROPOSED, WHICH WILL USE THE SELF-CONSISTENT FIELD APPROACH TO MULTIPLE SCATTERING. RESULTS WIL BE USED TO PREDICT ACOUSTIC SCATTERING SIGNATURES AS A FUNCTION OF THE ACOUSTIC AND TURBULENCE PROPERTIES OF THE SCATTERING SYSTEM. PROJECT OBJECTIVES INCLUDE A DETERMINATION OF THE COHERENT FIELD (MEAN FIELD) AS WELL AS ...

A quality simulation which allows a user to simulate the acoustic emissions in a multi-source environment and then study the effects these conditions have on a set of acoustic sensors would be of great value. As acoustic sensors technology continues to advance with robust algorithms for detection, tracking and identification as well as high performance hardware providing real-time operation, thes ...

THIS PROJECT ADDRESSES SYSTEMS TO REDUCE NOISE AND VIBRATIONS EMANATING FROM AUXILIAIY POWER UNITS (APUS) WHICH ARE BEING INITEGRATED INTO ARMY VEHICLES AND SHELTERS. EXCESSIVE NOISE AND VIBRATIONS ARE HARMFUL TO AND HINDER THE EFFECTIVENESS OF OPERATORS AND OCCUPANTS. IN MILITARY EQUIPMENT, IT IS ALSO BENEFICIAL TO AVOID EMANATIONS THAT MIGHT BE USED AS DETECTION SIGNATURES . THIS EXPLORATORY DEV ...

Physical Sciences Inc. (PSI) proposes to show the feasibility of using a novel, spectrally-selective IR imager for the passive standoff detection of chemical agents and hazardous chemicals. The concept is based on the insertion of a tunable etalon into the field-of-view of an IR imaging system. The approach takes advantage of recent advances in the development of staring IR focal plane arrays, w ...

This project applies a combination of Artificial Neural Networks (ANN), Genetic Algorithms (GA), and CAD software to the problem of optimum armor design. Previous work for TACOM has established the efficacy of ANN/GA as applied to the problem of 1-D armor design. This new work will extend the concept to full 3-D vehicle geometries (CAD models). The CAD part of the code will handle the 3D data d ...

The proposed effort is directed at achieving Automatic Target Cueing (ATC) performance at levels which are essential for near term system deployment. The performance required for deployment is beyond the capability of current systems. The design emphasis is to have robust performance under a full range of operating conditions, and to use techniques which lead to efficient real time implementatio ...
