Abstract :
The order statistics cell averaging (OSCA) constant false alarm rate (CFAR) and the order statistics greatest of (OSGO) CFAR detectors have the advantages of the order statistics (OS) CFAR detector, while the processing time of the OSCA and the OSGO CFAR detectors is less than that of the OS CFAR detector. This paper describes the exact formulas of the false alarm and the detection probabilities of CFAR detectors based on OS employing M-pulse noncoherent integration for partially correlated chi-square targets with two and four degrees of freedom.
