Training sample selection for space–time adaptive processing based on multi-frames [PDF]
The Journal of Engineering, 2019 As training samples are not identically distributed with cell under test (CUT) in heterogeneous environments, the performance of space–time adaptive processing (STAP) to suppress clutter degrades. To improve the performance of STAP, this study proposes a
