Abstract:

RADAR TARGET CLASSIFICATION CAN ENABLE IMPROVED ALLOCATION OF BATTLEFIELD RESOURCES, SUCH AS ASSIGNING WEAPONS TO THE MOST IMPORTANT CLASSES OF TARGETS. EXPERIMENTS HAVE SHOWN THAT GROUND VEHICLES AND HELICOPTERS HAVE DISTINGUISHING SPECTRAL COMPONENTS IN THEIR DOPPLER SIGNATURES. THESE KEY SPECTRAL FEATURES CAN BE MUCH WEAKER THAN THE UNWANTED CLUTTER ECHOES. CONSEQUENTLY, TARGET CLASSIFICATION IN A HIGH CLUTTER ENVIRONMENT REQUIRES FREQUENCY SELECTIVE FILTERING TO SEPARATE WEAK SPECTRAL FEATURES FROM THE STRONG CLUTTER. IT IS ALSO DESIRABLE TO RESOLVE SIGNALS AND CLUTTER WHICH ARE CLOSELY SPACED IN FREQUENCY AS MIGHT OCCUR WITH SLOWLY MOVING VEHICLES. EXISTING CLUTTER REJECTION TECHNIQUES, WHICH USE WEIGHTED FAST FOURIER TRANSFORM (FFT) PROCESSING, SUFFER FROM DEGRADED FREQUENCY RESOLUTION. A NEW POWERFUL TECHNIQUE OF SPECTRUM ANALYSIS BASED ON STOCHASTIC REALIZATION CONCEPT IS PROPOSED HERE WHICH IS EXPECTED TO PROVIDE HIGHER RESOLUTION SO THAT SLOWER-MOVING TARGETS CAN BE CLASSIFIED IN A HIGH CLUTTER ENVIRONMENT. THE PERFORMANCE OF THE RESULTING ALGORITHM WILL BE COMPARED TO THE STANDARD FFT APPROACH. THE PROPOSED STEPS TOWARD THE MAJOR OBJECTIVE ARE (1) MATHEMATICAL MODELING OF THE PROCESS, (2) PERFORM STATE-OF-THE-ART SURVEYS ON KEY RADAR TECHNOLOGY AREA, (3) ALGORITHM DEVELOPMENT AND TESTING, AND (4) SURVEY AND EVALUATE CLASSIFICATION ALGORITHMS. RAYTHEON CO AT WAYLAND, A LEADER IN RADAR TECHNOLOGY, WILL SUBCONTRACT IN THIS EFFORT.
