CFAR radar image detection in pulse jamming

It is shown that the appearance of strong pulse jamming in the reference window causes drastic degradation in the performance of CA CFAR (cell averaging constant false alarm rate) binary integration processors. The technique for pulse jamming suppression employed in this work is the use of filters matched to a broadband pulse with a large time-bandwidth product. In particular, the situation when the duration of broadband pulse transmission with phase-code-modulation and the average repetition interval of pulse jamming are commensurable, is considered in the paper. The mathematical formulas for analysis of the conventional CA CFAR binary integration processor in conditions of pulse jamming are derived for the case when the broadband pulse transmission is used. In addition, the possibility for real-time implementation of the CA CFAR binary integration processor over a multiprocessor system based on signal processors ADSP-21062, is analytically evaluated. The computation cost is defined as the number of signal processors and computation steps necessary for real-time implementation of the CA CFAR binary integration processor
