Abstract

Abstract: The geometry of every bistatic airborne radar configuration is analysed. A clutter mode with the variable azimuth angle and bistatic range is presented. A formula for calculating the Doppler frequency of receiving clutter in any bistatic configuration is deduced. It is an efficient tool for bistatic clutter analysis. And then a STAP approach to compensating the angle-Doppler difference of mainlobe clutter according to every ambiguous range apart is proposed. The problem of bistatic clutter suppression is solved perfectly.

Key words: clutter suppression, STAP, angle-Doppler compensation
