CFAR detectors in presence of jammer noise

Cell Averaging (CA)-CFAR detector is an optimum detector under the assumption of Rayleigh distributed homogenous noise background, but in presence of clipped jamming noise, it does not have the best performance. In this paper, we compare CA, GO, SO, OS, OSGO and OSSO conventional CFAR detectors to obtain superior CFAR detector in clipped jamming noise. Simulation results show that the OS-CFAR detector not only provides low loss CFAR performance in exponential background but also performs better than that of CA in clipping jammer noise situations. On other hand, by using OS detector instead of CA detector in radar, it saddles about 3dB more loss to jammer noise generator.
