A Method for Ground Moving Target Indication and Velocity Estimation Based on InSAR System

摘要：

For InSAR system, the increasing clutter degree of freedom (DOF) with the terrain is caused by long cross-track baseline. It degrades the performance of Ground Moving Target Indication (GMTI) greatly. In this paper a new method based on InSAR system is proposed for GMTI and Velocity Estimation. In our approach, the joint pixel technique is adopted to improve the coherence of clutter. In this way the clutter can be well cancelled. For the velocity estimation, neighboring pixel pairs is used to compensate the terrain interferometric phase. Therefore, the accuracy of velocity estimation can be improved. Stimulation experiments illustrate the effectiveness of the proposed algorithm.
