The focus of this paper is on the detection and velocity estimation of moving targets in single-channel SAR images. In particular, for detection purpose, a non coherent change detection technique is proposed and its theoretical performance is investigated. Concerning the velocity estimation, an analytical model relating the observed and real cross-range velocity is derived and used for those targets having radial motion. The theoretical performance analysis and the results obtained against real SAR data show the effectiveness of the proposed approach.
