A Novel CFAR Threshold Estimated Method for Coherent Integration Detector of PD Radar Seeker
Because of the imperfect model of the clutter, as well as the limited samples, there is always a wide performance gap between the theoretical model and the practical result for the constant false alarm rate(CFAR) detector of coherent radar in Range-Doppler domain. A novel method of estimating the detection threshold is proposed in this paper. The method is based on the least square criteria and derived from the relationship between the CFAR detection threshold and the probability of false alarm. Simulation results confirm the validity of the proposed method.
