Method for detecting ground moving target with range migration

For airborne radar detecting ground moving target, the range migration of the moving target was often ignored. However, for the cases of high relative speed between the radar and the target, the range migration should be considered, especially for high range resolution (HRR) airborne radar. Since the range migration can dramatically reduce the performance of detecting the moving target for airborne radar, the effect of range migration must be removed. In this paper, the data model of moving target with range migration is discussed, and a STAP method is proposed for detecting the moving target with range migration. Simulation results show that the proposed method can remove the range migration of all moving targets simultaneously, and improve the detection capability for the ground moving target with range migration.
