In the heterogeneous clutter and target rich environments, the conventional statistical space-time adaptive processing (STAP) methods are confronted with the problem of the lack of valid training samples, which may result in the performance degradation in clutter rejection. Thus, in this paper, a generalized sample weighting method in angle-Doppler domain (GSWADD) is presented and hence an implementation...
The range ambiguity results in the invalidation of space-time adaptive processing (STAP) methods for airborne non-side-looking array radar. To overcome this problem, in this paper, a separation approach for the angle-Doppler spectrum of far-range clutter (FRC) and near-range clutter (NRC) is proposed. Firstly, by the fact that the FRC spectra almost completely overlap, the proposed method obtains...
Prolate spheroidal wave function (PSWF) method could improve the target detection performance for space-time adaptive processing (STAP) in nonhomogeneous environment. However, it may be ineffective with system parameter error. In this paper, we correct the system parameter with clutter spectrum analysis. Since contaminated samples contained in the secondary data set have detrimental impact on this...
