| 摘 要： | 1. INTaODUCTIONThe task of radar receiver is to detect the useful targets in clutter bedground. In the automatic radax detedionsystem, the decision whether there eclat targets is made according to the decision criterion by using a detedinntbleshold. For a fixed detection threshold, if the interference power level increases several dB, the false alarmrate will seriously increase. Therefore, to extract the useful signals in strong interference environment, hot Onlyadequate signal to noise r…

| Abstract: | This paper studies the performance of the GOSGO and GOSSO CFAR detectors 1] in clutter edge situation. The authors derive the analytic expressions of the false alarm probabilities in that situation, analyze their performances against clutter edge, and compare them with the OS, CA, GO and SO detectors. The results show that GOSGO possesses better performance than GO for countering clutter, but the performance of GOSSO is very unideal. |
