Ground Moving Target Indication Based on Along Track Airborne InSAR with Two Antennas
顺轨双天线机载InSAR的地面运动目标检测研究

The Ground Moving Target Indication(GMTI) is investigated based on along track high resolution airborne InSAR with two antennas. The two antenna interferometric processing is used to suppress ground clutter. The concept of moving target imaging is introduced for GMTI of high resolution InSAR with longer synthetic aperture time. The range migration correction and refocus processing for moving target signals are implemented to improve the signal-noise rate and signal-clutter rate for their detection and velocity measurement. The processing results of simulated InSAR data show the effectiveness of the new method.
