| 摘 要： | 基于高分辨率顺轨双天线机载InSAR，研究了地面运动目标检测问题。采用双通道干涉处理，抑制地面静止杂波。针对高分辨率InSAR合成孔径时间较长的特点，将运动目标成像处理的概念引入运动目标检测过程，对运动目标信号实施距离徙动校正后，再聚焦成像，从而改善检测信噪比和信杂比，并进一步提高测速精度。InSAR仿真数据的处理结果表明了该方法的有效性。

| Abstract: | 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. |
