摘　　要：本文研究了三孔径干涉合成孔径雷达（INSAR）地面动目标检测和成像处理技术，即应用三通道杂波抑制干涉（CSI）对消地杂波后进行地面动目标检测，确定动目标的真实方位和径向地速并聚焦成像处理．论文详细分析了三通道杂波抑制处理的机理，研究了了地面动目标检测，确定真实方位和径向地速的方法，给出了INSAR地面动目标聚焦成像处理中的一种实现方法．给出了一组典型计算机模拟结果，验证了该技术的正确性和可行性．This paper studies the three-aperture interferometic synthetic aperture radar (INSAR) detecting and imaging processing technique of the moving groUnd targets, which uses three-port clutter suppression interferometry (CSI) processing to cancel ground clutter, to detect the moving ground targets and simultaneously determine their true azimuth location and radial ground speed and to form the focus moving ground targets' images. This paper describes in detail the principle of the three-port clutter suppresion interferometry processing, studies the approach to detect the moving ground targets and determine the true azimuth location and radial ground speed and presents a kind of method using INSAR to form the focus moving ground targets' images. Finally, some typical computer simulation results are presented, which illustrate this technique's availability.
