Abstract

Abstract

Focusing on the range ambiguity of the moving target in airborne radar system, a novel Space-Time Adaptive Processing (STAP) approach based on frequency diverse array configuration is proposed for range ambiguous clutter suppression. In the proposed method, the controllable degree-of-freedom is exploited, which is introduced by the frequency diverse. The range ambiguity number is incorporated into the steering vector of the target signal. By separating the different range ambiguous range region in the spatial frequency domain, the target can be detected separately within each range region and thus range ambiguity can be resolved. By using the proposed method, giving only one pulse repetition frequency, the moving target can be detected and the range ambiguity can be resolved simultaneously, which improves the performance of airborne radar evidently. Simulation results demonstrate the effectiveness of the proposed method.
