| 摘 要： | 首先讨论基于ATI与DPCA的两天线SAR的干涉图像对地面动目标进行检测的过程。根据SAR产生回波的原理，产生动B标，地面杂波及假目标的干扰信号。经仿真分析，在干扰能量较小时，真实的动目标还可以检测到，但是目标速度，方位参数估计出现错误；当干扰能量较大时，检测出许多虚假目标，动目标淹没其中，可以得到较好的干扰效果。

| Abstract: | It is discussed moving targets detection using the dual-channel images based on ATI and DPCA. By the principle of creating target echoes, ground clutter and false target＇ s echoes are produced. By the simulation, when jamming energy is lower, moving targets can be found with wrong rate and position. When jamming energy is higher, many false targets appear covering real moving targets, and a better effect can be achieved. |
