This is due to the coupling of the cross-range position to the target radial velocity and the fact that the moving target and ... the moving targets detected in the SAR image are not their actual locations on the ground. In fact, recall that the detection of the moving targets in the SAR image depends on the fact that they ... whether of the ground itself or from moving targets embedded within the scene.

Thus, the moving targets have to meet the dual thresholds: one in power and the other in phase deviation [8]. If the power threshold is set at 15 dB in...
