Abstract

In this paper, we study the sensitivity of cell-averaging constant false alarm rate (CA CFAR) processors towards the change of input distribution (Poisson and binomial distribution) of pulse jamming (PJ). We offer the mathematical expression for calculating the parameters of CA CFAR detectors in the entire area of the probability for the appearance of strong pulse jamming. The original results in the present work concern the determination of the sensitivity expressions of the probability of detection, probability of false alarm and the average decision threshold (ADT) for CA CFAR detectors, towards the change of distributed pulse jamming. The results show that a CA CFAR processor has high losses when the scale factor is chosen incorrectly. Research is performed in a MATLAB environment.
