Applicability analysis of CFAR algorithm for landmines detection applied to vehicle-mounted forward-looking SAR

For the vehicle-mounted forward-looking synthetic aperture radar (SAR), detecting algorithms should be effective, robust and real-time. This paper proposed a fast statistic detecting algorithm based on circulatory iteration. We also presented feasible methods to select the optimal parameters of constant false alarm rate (CFAR) detector. Experiment results showed that our algorithm had high detecting rate, low false alarm rate, good adaptability and much less computation load.
