雷达目标的高分辨率距离像反映了目标的散射中心在径向的分布,该分布与目标的几何外形密切相关。文中将一帧距离像看作一个序列,用提出的一种新的算法对该序列进行预处理,然后求出预处理序列的Lempel-Ziv复杂度,将其用于目标识别。试验结果证明了该识别方法的有效性。

High range resolution profiles (HRRPs) give the distribution of the scatterers of radar targets along the radial dimension, which is closely related to the target geometry. In this paper, an HRRP, seen as a series, is pre-processed by using a newly introduced algorithm, then the Lempel-Ziv complexity of the pre-proeessed series is calculated and is used for target recognition. The experimental results demonstrate its effectiveness.
