DISTRIBUTED ARRAY RADAR DEMONSTRATION

THE OBJECTIVE IS TO FURTHER DEFINE AND SPECIFY A GROUND-BASED EXPERIMENT DESIGNED BY INTERSPEC, THAT WILL PROVE THAT A DISTRIBUTED ARRAY RADAR CAN OPERATE COHERENTLY ON TRANSMIT AS WELL AS RECEIVED WITH FULL TWO-WAY GAIN. COHERENT OPERATION ON RECEIVE HAS ALREADY BEEN DEMONSTRATED BY THE UNIVERSITY OF PENNSYLVANIA VALLEY FORGE RESEARCH CENTER (VFRC) AND INTERSPEC. THE EXPERIMENT TO BE DESIGNED WILL DEMONSTRATE FULL COHERENT RECEIVE GAIN IN A WIDELY DISTRIBUTED ARRAY, COHERING ON CLUTTER AND ON COLLECTIONS OF POOR PHASE SYNCHRONIZING SOURCES, FULL COHERENT TRANSMIT-RECEIVE GAIN, COMPARATIVE PERFORMANCE EVALUATION OF SELF-SURVEYING AND SELF-COHERING TECHNIQUES FOR TWO-WAY COHERENCE, SYSTEM SURVIVABILITY, REMOVAL OF SIDELOBE ARTIFACTS, ADAPTIVE SIDELOBECLUTTER CANCELLATION, AND ADAPTIVE JAMMER CANCELLATION. THE PROPOSED EXPERIMENTS REPRESENT THE CULMINATION OF TWELVE YEARS OF RESEARCH AND DEVELOPMENT OF TECHNIQUES FOR SYNCHRONIZING AND COHERING LARGE, DISTRIBUTED, PHASED ARRAY RADARS. A DISTRIBUTED SPARSE ARRAY REPRESENTS AN IDEAL WAY TO ELIMINATE SURFACE CLUTTER AND REDUCE CLUTTER DOPPLER SPREAD IN A SPACEBORNE OR AIRBORNE AIR DEFENSE RADAR.
