Abstract

MFI-FET-frequency cell-averaging CFAR processors are discussed. The assumption that the clutter sample in the test cell and the reference cells are dependent and identically distributed (IID) is shown to be no longer valid for the frequency cell-averaging CFAR processor in medium PRF airborne pulse Doppler radars. A hybrid method of analytical computation and Monte-Carlo simulation for quantifying the processor performance is described. The effect of various MTI cancelers and weighting forms on the detection performance under different conditions of clutter is analyzed
