PERFORMANCE ANALYSIS OF OSGO AND OSSO CFAR DETECTORS UNDER PEARSON DISTRIBUTED CLUTTER

摘要

In this paper, the detection performance of OSGO and OSSO CFAR detectors embedded in heavy-tailed Pearson distributed clutter is analyzed. We derive the closed mathematic form expressions of probability of false alarm rate and detection probability of the two CFAR schemes. While the processing speed of OSGO and OSSO CFAR is two times of that of OS CFAR, simulation results indicate that OSGO CFAR detector's performance is very close to OS, and OSSO CFAR offers better and robust detection performance than OS CFAR in multiple-target situation.
