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. -
