A Signal Processing Method for Airborne Three-channel SAR-GMTI

摘要：

Aiming at airborne three-channel SAR-GMTI system,a signal processing method based on Clutter Suppression Interferometry(CSI) is presented including the processing diagram and the principle of clutter suppression.Channel calibration is proposed to correct the magnitude and phase imbalance between inner channels utilizing the test signal,SAR imaging and clutter cancellation are done successively,finally the accurate target parameters (location and velocity) are obtained. The signal processing approach which has been applied in real data proved its good performance and turned out to be efficient.
