Space-time adaptive processing (STAP) refers to a class of signal processing techniques used to process returns of an antenna array radar system [4]. STAP algorithms are designed to extract desired target signals from returns comprised of Doppler shifts, ground clutter, and jamming interference. STAP simultaneously and adaptively combines the signals received on multiple elements of an antenna ...

Combined monostatic clutter (MSC) and terrain scattered interference (TSI) pose a diicult challenge for adaptive radar processing. Mitigation techniques exist for each interference alone but are insuucient for their combined effects. Current approaches separate the problem into two stages where TSI is suppressed rst and then MSC. The problem with this cascade approach is that during the initial...

ADAPTIVE SPACE-TIME PROCESSING FOR DIGITAL MOBILE RADIO COMMUNICATION SYSTEMS

This paper addresses the issue of employing space-time adaptive processing (STAP) prior to doppler filtering in radar systems. When STAP beamformer processing is applied to spatial/temporal samples that include successive radar pulses, the adaptive weights can cause modulation (spreading) of the desired target doppler. In this paper, a linearly constrained adaptive beamformer is proposed that e...
