ABSTRACT
Space-time adaptive processing (STAP) is a multidimensional filtering technique developed for minimizing the effects of various kinds of interference on target detection with a pulsed airborne surveillance radar. The most common dimensions, or filtering domains, generally include the azimuth angle, elevation angle, polarization angle, Doppler frequency, etc. in which the relatively weak target signal to be detected and the interference have certain differences. In the following, the STAP principle will be illustrated for filtering in the joint azimuth angle (space) and Doppler frequency (time) domain only.
