The focus of this paper is on resolving some of the ambiguity inherent in locating moving targets in single-channel SAR images. Detection of moving targets 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. Comparison of the estimated target parameters with the road pattern as provided by a GIS containing the local road network is relied upon for target re-location. The method and the results of testing on real images are presented and discussed.

The focus of this paper is on resolving some of the ambiguity inherent in locating moving targets in single-channel SAR images. Detection of moving targets 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. Comparison of the estimated target parameters with the road pattern as provided by a GIS containing the local road network is relied upon for target re-location.
