Performance of decentralized L-CFAR detection in inhomogeneous background

The problem of decentralized constant false alarm rate (CFAR) detection, wi th L-CFAR remote sensors, is considered. Following a previous paper, concer ning the design and the analysis of such detection structure in homogeneous environment, we now assume that a detector, designed to operate with homog eneous background, is affected instead by clutter edges and secondary targe ts entering the local sensor reference windows. For this inhomogeneous envi ronment, we derive dosed-form analytical approximations of the detector per formances. Results of computer simulations, which validate the derived form ulas, are provided.
