RDM算法应用于SAR动目标检测时参数选择原则

THE PARAMETER CHOICE OF RDM IN MTI-SAR

该文针对雷达系统方位向波束较小的情况下RDM的参数选择问题进行了探讨,指出了RDM参数选择的决定因素,并将这种原则应用于雷达方位向波束仅为9°的LSAR,实验证明也可以达到较好的检测效果。

In this paper, the question of the parameter choice of RDM (reflectivity displacement method) for the radar system that has a narrow azimuth antenna beam is discussed and the important factors that determine the choice of the parameters are proposed. Experiments using raw data of L SAR that has an azimuth beam of only 9° show that good detection result can be achieved when applied these principles for parameter choice.
