SPACE TIME ADAPTIVE PROCESSING FOR AI RADARS

AIRBORNE INTERCEPTOR RADARS AT UHF OR L-BAND WITH CONFORMAL WINGMOUNTED ARRAY ANTENNAS AND DIGITAL SIGNAL PROCESSING ARE OF INTEREST FOR FUTURE SYSTEMS. ADAPTIVE CONTROL OF THE ANGLE/DOPPLER RESPONSE OF THESE RADARS, USING ARRAY ELEMENT OUTPUTS, MULTIPLE BEAM OUTPUTS, OR SUB-APERTURE OUTPUTS PROVIDES A POSSIBLE METHOD OF DETECTING AND TRACKING LOW CROSS-SECTION TARGETS IN GROUND CLUTTER. THESE TECHNIQUES ARE ALSO EFFECTIVE IN MIXED CLUTTER/JAMMING ENVIRONMENTS. THIS STUDY WILL COMPARE THE PERFORMANCE AND COMPLEXITY OF ALTERNATIVE ALGORITHMS FOR DETECTING AND TRACKING TARGETS WITH ADAPTIVE AI RADARS.
