The focus of this paper is on detection, tracking, confirmation and velocity estimation of moving targets in single-channel SAR images. Detection of moving target relies on a technique named doublet detection, while tracking is based on velocity estimation in the range-Doppler plane; confirmation of the target as a mover is enabled by two specifically developed tests on the range-Doppler target path. Velocity estimation is performed through a theoretically derived formula. The method and the results of extensive testing on real images are presented and discussed.
