Performance of Distributed OSGOR CFAR Detector with Nonconherent Integration

A novel distributed detector, called OSGOR detector, is proposed for multiple pulse noncoherent integration. In this detector, each sensor transmits its test cell sample and a designated order statistic (OS) of its reference observations surrounding the test cell to the fusion center. At the fusion center, the global noise power level is obtained with greatest of (GO) processing. Without knowing the level of Gauss noise, the closed-form expressions of probabilities of false alarm (Pfa) and probabilities of detection (Pd) about the four types of Swerling target fluctuating models (I, II, III and IV) are derived. The proposed detector´s detection performance is performed with numerical simulation
