CFAR detection of moving target for Monopulse-SAR based on statistical analysis of complex monopulse ratio
An efficient approach to achieve ground moving target indication (GMTI) for synthetic aperture radar (SAR) is to use the Monopulse-SAR system. This paper examines the statistics of complex monopulse ratio (CMR) for SAR/GMTI model when complex Gaussian clutter-plus-noise is considered. The two dimensional probability density function (pdf) of CMR is analyzed in detail. An automatic constant false-alarm rate (CFAR) detector with the probability of false alarm given in a closed-form for moving targets is provided and extended to a multi-CMRD form to further improve the final detection performance. Experimental results are presented to examine the detection performance and validate the theoretical analysis.
