A PROTOTYPE OF ESM/ELINT RECEIVER SYSTEM UTILIZING ACOUSTIC CHARGE TRANSPORT (ACT) TECHNOLOGY IN AN ADAPTIVE CHANNELIZER IS PROPOSED. THE TYPES OF ACT TECHNOLOGY TO BE EXPLOITED IN THIS DEVELOPMENT ARE TUNABLE FILTERS WITH PROGRAMMABLE BANDWIDTHS AND ADJUSTABLE DELAY LINES FOR DELAY LINE DISCRIMINATORS. A VERY LONG DELAY USING ACT TECHNOLOGY WILL ALSO BE INVESTIGATED. THIS ADAPTIVE RECEIVER BUILDS ...

THIS PROPOSAL INVOLVES THE DEVELOPMENT OF TECHNIQUES FOR AUTOMATED PROCESSING OF SNYTHETIC APERTURE RADAR (SAR) IMAGERY. SPECIFICALLY, THIS TASK INVOLVES FINDING ALTERNATING CURRENT (AC) POWER LINES AND RELATED STRUCTURES FROM HIGH-RESOLUTION AIRBORNE SAR (ASAR) IMAGES. WE WILL IDENTIFY AREAS FOR IMPROVEMENT AND DEVELOP NEW TECHNIQUES AS NECESSARY TO STRENGTHEN WEAK AREAS. WE WILL ESTABLISH A METH ...

COMPOSITES HAVE ESTABLISHED THEIR ADVANTAGEOUS FOR HIGH PERFORMANCE AND WEIGHT REDUCTION, PARTICULARLY IN TENSION-LOADED STRUCTURES LOADED. THESE MATERIALS POSSESS HIGH STIFFNESSES AND TENSILE STRENGTHS COMBINED WITH LOW DENSITY, AND THEY HAVE BECOME THE MATERIAL OF CHOICE IN NUMEROUS HIGH PERFORMANCE APPLICATIONS. THE SAME CANNOT BE SAID FOR COMPRESSIVE PROPERTIES OF THESE MATERIALS, WHICH ARE OF ...

MAN-PORTABLE ELECTRONICS EQUIPMENT SUCH AS THE MINI GLOBAL POSITIONING SYSTEM RECEIVER IS CURRENTLY POWERED BY HEAVY CHEMICAL BATTERIES. A WIND-UP SPRING DEVICE, CAPABLE OF PRODUCING 4W AT 12V FOR 5 MIN AT ONE WINDING, WOULD BE A DESIRABLE SUBSTITUTE FOR BATTERIES. UNFORTUNATELY, CALCULATIONS SHOW THAT THE WEIGHT AND BULK OF A SPRING MECHANISM WOULD BE UNACCEPTABLE. INSTEAD, A SMALL, HIGHLY EFFICI ...
