Abstract :
Provides a novel multi-channel SAR moving targets detection and image (MTDI) method. After clutter is cancelled by using three apertures, two ways of signals through which moving targets can be detected are gained. Then Doppler centroid and Doppler frequency rate can be estimated, so both the real positions and velocities of moving targets will be acquired. Finally some typical computer simulation results are presented which illustrate the method´s validity.
