Abstract: In this paper CA CFAR, excision CFAR, CA CFAR BI, excision CFAR BI and API CFAR processors in strong pulse jamming (PJ) are discussed . We investigate the influence of the scale factor over probability of false alarm and detection probability in strong PJ for one-dimensional CFAR processors. The efficiency of one- and two-dimensional CFAR processors by using the average decision threshold (ADT) approach is evaluated. The results for the ADT are received analytically using the Monte-Carlo method and the probability functions (SNR). The researches are performed in MATLAB environment.
The experimental results show that API CFAR processors are most efficient for probability of appearance of pulse jamming (from 0 up to 0.5). For we recommend binary integration after the CFAR processor.
