IMPROVED RADAR TRACKING AGAINST CHAFF COUNTERMEASURES

THIS PROPOSED PROGRAM IS TO INVESTIGATE THE FEASIBILITY OF USING UNIQUE FILTERING TECHIQUES TO PROCESS PULSE-TO-PULSE RCS AND PHASE DATA TO TRACK AN AIR VEHICLE IN THE PRESENCE OF CHAFF. THE PROPOSED TECHNIQUE WOULD PERMIT TRACKING THE AIRCRAFT WITH OR WITHOUT THE PRESENCE OF CHAFF. IT IS ANTICIPATED THAT THIS INSTRUMENTATION COULD BE ADDED TO ANY COHERENT OR SEMI-COHERENT RADAR AND BE FAR SUPERIOR TO THE PRESENT MTI AND OTHER ANTI-CLUTTER TECHNIQUES. THE FEASIBILITY WILL BE INVESTIGATED BY USING ACTUAL PULSE-TO-PULSE RCS AND PHASE DATA COLLECTED IN THE TRIAL MACE III PROGRAM IN 1982 WHEREIN LARGE AMOUNTS OF DATA WERE COLLECTED ON FIVE TYPES OF HELICOPTERS AND 15 TYPES OF FIXED WING AIRCRAFT.
