Abstract	The presence of strong pulse jamming in a reference window used by Cell-Averaging CFAR detectors for noise power estimation can cause drastic degradation in performance even if the CA CFAR detectors employ binary integration. The technique for pulse jamming suppression discussed in this work is the use of filters matched to a broadband transmitted pulse in combination with an excision CFAR detector where strong samples are excised from the reference window prior to the cell-averaging operation. In particular, the excision CEAR detector with binary integration is considered in situation when the duration of broadband pulse transmission with phase-code-modulation and the average repetition interval of pulse jamming are commensurable. The mathematical formulas for analysis of the excision CFAR binary integration processor are derived for the case of broadband pulse transmission in the presence of pulse jamming. In addition, the possibility for real-time implementation of the excision 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 excision CFAR binary integration processor.
