In this paper

a new method of moving target detection

radial velocity estimation and relocation based on dual-aperture antenna along-track interferometric SAR is proposed.The principle and realization of clutter cancellation

moving target detection

radial velocity estimation and relocation are presented based on the analysis of clutter cancellation necessity.After constant false alarm rate(CFAR)processing

the moving targets are separated and the detection process is realized by comparing the cancellation extent between the residue SAR image and the original SAR image.In the meanwhile

the radial velocity estimation and relocation of moving targets can be performed by using the clutter cancellation characteristics of the residue SAR image.This method features significant clutter cancellation and can perform the detection

radial velocity estimation and relocation of moving targets masked by ground clutters.Simulation results show that the method proposed in this paper is effective.
