Abstract

This paper presents a unique false alarm mitigation approach for nonhomogeneous clutter, which is problematic for digital radars with increased sensitivity. A clutter map is formed containing estimates of the two parameters for the K-distribution. The map applies the new thresholds to the data. The false alarm rate is reduced by a factor of 1000 due to the improved accuracy in modeling the clutter distribution tail.

基于k分布的高灵敏度数字雷达杂波处理
针对非均匀杂波的虚警抑制问题,提出了一种独特的非均匀杂波虚警抑制方法。形成一个杂波图,其中包含k分布的两个参数的估计。该映射将新的阈值应用于数据。由于提高了对杂波分布尾部的建模精度,虚警率降低了1000倍。
