Abstract
DYNETICS PROPOSES A NOVEL PROCESSING TECHNIQUE FOR INCREASING THE RANGE RESOLUTION CAPABILITY OF A LARGE CLASS OF RADARS. THIS TECHNIQUE, LINEAR FREQUENCY MODULATION ENVELOPE PROCESSING (LFMEP), ALLOWS RANGE RESOLUTION FOR LFM SIGNALS THAT IS NOT LIMITED IN THE USUAL WAY BY THE WAVEFORM'S BANDWIDTH. THEORETICALLY, THE TECHNIQUE IS ABLE TO RESOLVE TWO TARGETS SEPARATED BY AS LITTLE AS 10 WAVELENGHTS OF THE CARRIER FREQUENCY. THHIS CAPABILITY IS ACHIEVED BY PROCESSING THE ENVELOPE OF SUCCESSIVELY RECEIVED LFM WAVEFORMS AND DOES NOT REQUIRE PULSE-TO-PULSE COHERENCY OF THE TARGET. DYNETICS PROPOSES TO ADVANCE LFMEP AND DEMONSTRATE ITS CAPABILITY FOR A RADAR SYSTEM. DURING PHASE I, DYNETICS' OBJECTIVES WILL BE TO COMPLETE DEVELOPMENT OF THE BASIC TECHNIQUE, TO EXTEND THE METHOD FOR MULTIPLE AND FLUCTUATING TARGETS, AND TO PURSUE ENHANCEMENTS INCLUDING ALTERNATIVE WAVEFORMS AND POST-PROCESSOR APPLICATION. THIS RESEARCH WILL THEN PROVIDE THE REQUISITE BACKGROUND FOR FIELD-TESTING IN A PHASE II TASKING.
