A Non-homogeneous STAP Approach Combined with RD-ATI Technique

摘要：

In this paper,a non-homogeneous Space-Time Adaptive Processing (STAP) approach is proposed.In the approach,Range-Doppler domain ATI (RD-ATI) technique is used as a Non-Homogeneous Detector (NHD) which provides prior knowledge of moving targets,then Power select Training (PST) method is employed to restrain clutter power non-homogeneous,and Frequency Domain substitution (FDS) method used to eliminate the discrete interference. The approach improves conventional STAP performance significantly and greatly reduces computational burden,which has a great practical value. The result of real data from a three-channel SAR/GMTI system shows efficiency of the approach.
