A Sort of Improved VI CFAR Detector

In order to obtain the better detection performance under the varied clutter background,a sort of improved variable indication(VI) CFAR detector was given,where the corresponding advantages of MLVI CFAR and OSVI CFAR detectors were taken and the idea that the VI CFAR can select the varied detectors automatically under the background uniform extent was based on.Theoretical analysisand simulation results show that the performance of the proposed detector is typically identical with MLVI CFAR under the uniform background,well capable of antimulti targets under the background of multi-targets,better capability of CFAR control under the background of clutter edge and less computation,being a sort of robust detector.
