Abstract
Non-Rayleigh clutter statistics result when sea or ground clutter are viewe d with resolution radars (pulse widh < 0.5 mu s) at low grazing angle (phi < 5 degrees). In this paper, we consider the problem of Clutter Map Constan t False Alarm Rate detection (CMAP-CFAR) in Weibull distribution with a sha pe parameter known. The target is assumed to be fluctuating according to Sw erling I model. Closed-form expressions for the probabilities of detection and false alarm in terms of shape and scale parameters are determined and t he performance of the system is investigated and analyzed.
