摘　　要：在军事应用场合中,SAR除了能获得高分辨率图像外,还具有对地面运动目标进行探测、跟踪和定位的能力。结合试验用SAR/MTI雷达的具体情况,对采集的数据运用通道校正和均衡处理等技术,并在图像域进行杂波抑制干涉处理来提高系统的杂波对消能力。通过计算机仿真和三孔径SAR/MTI实测数据的处理,证明该处理方法能有效地从地杂波中检测出地面慢速运动目标的运动轨迹。In military application, besides high resolution images, the SAR can also provide functions such as ground moving target detection, location and track. According to the characteristic of a SAR/MTI system with three antennas designed by ECRIEE, the channels equalizing technology and clutter suppression interferometry processing are applied to improve the clutter cancellation ability of the system. Computer simulation and real data processing results show that the proposed method is effective.
