Abstract

We focus on the effect of range and Doppler ambiguities on the ability to detect slow moving targets by STAP radar. This work has been conducted in the context of international projects such as SOSTAR and AMSAR.The detection of moving targets by a moving radar (air- or spaceborne) is seriously degraded by strong clutter returns. Space-time adaptive processing (STAP) techniques can implicitly compensate for the motion induced Doppler shift and thereby improves the capability of slow target detection. The effect of ambiguities on the target tracking capability of a STAP radar is discussed in conjunction with a companion paper by Koch (see Radar 2002, Edinburgh, Scotland, October 2002).
