MULTIPLE, INTEGRATED, ELECTRONICALLY STEERED ARRAYS (ESA) RADAR PERFORMANCE ENHANCEMENT

MULTI-DIMENSIONAL ADAPTIVE PROCESSING TECHNIQUES ARE PROPOSED TO DETECT LOW OBSERVABLE AIR-BORNE TARGETS IN DIFFICULT JAMMING AND CLUTTER ENVIRONMENT. THE PROBLEMS OF STRONG SIDELOBE JAMMING, MAIN-BEAM CLUTTER, SIDE-LOBE CLUTTER, RANGE/DOPPLER SPREAD OF CLUTTER, JAMMING GENERATED TERRAIN SCATTERED INTERFERENCE (TSI) ARE ADDRESSED IN THE PROPOSALS. THE COMBINATION OF SPATIAL, TEMPORAL AND SPECTRAL ADAPTIVE PROCESSING ARE PROPOSED TO SOLVE THESE PROBLEMS. TSI IMAGING TECHNIQUE IS PROPOSED WHICH USES THE JAMMING ENERGY TO DETECT THE TARGET. THE PROPOSED APPROACHES ARE SUPPORTED BY COMPUTER SIMULATIONS WITH THE SIMULATION RESULTS PRESENTED IN THIS PROPOSAL. THE WORK PLAN INCLUDES DETERMINATION OF THE PROCESSOR ARCHITECTURE, SYSTEM MODELING AND SIGNAL GENERATION, ALGORITHM DEVELOPMENT AND PROCESSOR SIMULATION, PERFORMANCE EVALUATION AND COMPUTATIONAL LOAD REDUCTION.
