Performance of excision switching-CFAR in K distributed sea clutter

In this paper a new CFAR detector which is composed of an excision processor and a switching-CFAR detector, in an environment with K distribution, has been introduced. The new detector is named an excision switching CFAR Performance of EXS-CFAR is derived and compared with the some other detectors like CA-CFAR, GO-CFAR and SO-CFAR for Swerling I target model in homogeneous and non-homogenous noise environments such as those with multiple interferes and clutter edges. The results show that EXS-CFAR detectors considerably reduce the problem of excessive false alarm probability near clutter edges while maintaining good performance in other environments.
