摘要: 該文針對(duì)雷達(dá)系統(tǒng)方位向波束較小的情況下RDM的參數(shù)選擇問(wèn)題進(jìn)行了探討,指出了RDM參數(shù)選擇的決定因素,并將這種原則應(yīng)用于雷達(dá)方位向波束僅為9的LSAR,實(shí)驗(yàn)證明也可以達(dá)到較好的檢測(cè)效果。

Abstract: 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. -
