Performance Analysis of OSAP-CFAR Detector in K Distribution Background

摘要

The OSAP-CFAR employs soft rule based on fuzzy logic to give better detection probability than that of OSGO and OSSO-CFAR detectors for Weibull clutter. However, studies show that the K distribution provides a better fit for many clutter situations. The performance of the OSAP -CFAR is studied and compared with OSGO and OSSO-CFAR for the Swerling II target model in K distributed clutter. The results represent that the detection performance of OSAP-CFAR detector is superior to that of OSGO and OSSO-CFAR detectors both in the homogenous background and in multiple interfering targets situations.
