Abstract :
The CFAR detector is an important part of radar processor. This paper studies and simulates the CFAR detection in pulse Doppler radar processor. We present a scheme of realization for the CFAR detector in processor. To cell averaging CFAR, we study the questions on the false alarm probability, discovery probability and CFAR loss etc. The influence of finite reference cells on false alarm performance is analyzed and the modified threshold coefficients are given. We obtain the CFAR loss under different amount of reference cells, the relation of the CFAR loss and relative threshold coefficients, and processor input SNR for a certain discovery probability. Additionally, we study influence of the other parts of the processor on performance of CFAR processing such as the influence of pulse compression on false alarm probability and etc.
