RECENT TREATY NEGOTIATIONS BETWEEN THE US AND THE USSR PLACE LIMITS ON THE SIZE AND LOCATIONS OF NUCLEAR TESTS. THESE LIMITS ARE PERCEIVED AS POTENTIAL INDUCEMENTS FOR THE USSR TO CONDUCT HIDDEN TESTS OUTSIDE THE TREATY REQUIREMENTS. ONE METHOD OF SECRETLY CONDUCTING TESTS WOULD BE TO PERFORM DECOUPLED TESTS IN LARGE HIDDEN UNDERGROUND CAVITIES. THE US MUST BE PREPARED TO QUICKLY AND EFFECTIVELY I ...

Mayflower Communications proposes to substantially improve the reliability of Global Positioning System (GPS) receivers under jamming using a combined adaptive antenna and temporal filter solution that incorporates low cost, small size, and low power requirements. The objective is to provide up to 50 dB of additional interference protection for both military and commercial GPS systems at an affor ...

This Phase I study proposes to address the problem of providing robust guidance, navigation and control in the presence of jamming on high dynamic platforms. Specifically, we propose an innovative all-digital system architecture that tightly integrates an adaptive antenna spatial/temporal filter with the GPS/INS receiver to form multiple simultaneous beam/null patterns - one for each satellite be ...

MICRO-ELECTRONIC FABRICATION TECHNOLOGIES HAVE RECENTLY BEEN APPLIED TO PRODUCE NOVEL MICRO-MECHANICAL DEVICES SUCH AS MOTORS, SENSORS, AND ACTUATORS. THEIR SMALL SIZE AND EASY INTEGRATION WITH MICROELECTRONICS INVITE INNOVATIVE RESEARCH, BUT THUS FAR FEW USEFUL APPLICATION CONCEPTS HAVE BEEN DEVELOPED. ONE DEVICE WITH WIDESPREAD APPLICATION WOULD BE AN ELECTRICALLY SUSPENDED MICRO-GYROSCOPE. THE ...

SatCon Technology Corporation proposes to develop the next generation power controller module aimed at the integrated control and power functions desired for the Power Electronics Building Block (PEBB) which has broad goverment and commercial interest. Building on power hybrid technology advances made by SatCon during participation in Chrysler Corporation's "Patriot" Hybrid Electric Race Car Prog ...

DARPA wishes to exploit MEMS technology to develop a tactical grade INS. SatCon is proposing to develop an angular rate sensor combined with an accelerometer which are microfabricated on a single "chip" using the LIGA lithographic process. The accelerometer element employs a rebalanced cantilever, oriented orthogonally to the substrate, while the rate sensor uses a vibrating cylinder sensitive t ...

The success of DoD's thrusts in Global Surveillance and Precision Strike depends critically on the ability to perform Automatic Target Recognition (ATR) and Hostile Target Identification (HTI). The technologies of modeling, sensor data fusion and adaptive intelligent image processing are key to the success of ATR and HTI. An innovative approach to intelligent model-based image processing and tar ...

We propose here new methods for system identification and active feedback control of axial flow compressors under conditions of incipient rotating stall and surge in the presence of inlet distortions. The nonlinear Moore-Greitzer model of rotating stall, which has proven useful for both simulation of rotating stall/surge dynamics of axial compression systems and for control design studies, will b ...

The detection and recognition of man-made objects under foliage conditions requires the use of VHF/UHF ultra-wideband (UWB) radars such as P-3/SAR system developed by ERIM for NAWC/AD and DARPA. At low frequencies and long wavelengths, most of the scatters are in the Rayleigh scattering region and their RCS is low, which enables foliage penetration. However, this also results in a small number o ...
