Novel clutter map CFAR algorithm with amplitude limiter

The traditional clutter map constant false alarm rate (CM-CFAR) detector is affected by interference and self-masking which will cause the low probability of detection. To solve these problems, a novel algorithm named clutter map CFAR with amplitude limiter (ALCM-CFAR) is proposed, in which the amplitude of the input signal is limited by a filter. The simulation results prove the effectiveness of ALCM-CFAR algorithm.
