| 摘 要： | 地球同步轨道合成孔径雷达(GEO SAR)编队飞行，是指2个或2个以上的搭载了合成孔径雷达的地球同步轨道卫星协同工作，组成一颗大的“虚拟卫星”，进而完成多项任务并降低风险。GEO SAR编队飞行形成的多通道可以用来进行动目标检测。空时自适应处理(STAP)在空-时二维平面上抑制杂波，完成强杂波背景下的动目标检测。在传统STAP算法的基础上，提出了基于GEO SAR编队飞行的对地面运动目标检测的方法，并通过仿真分析了该方法的性能。

| Abstract: | GEO synchronous Synthetic Aperture Radar(GEO SAR) formation means that two or more GEO satellites which carry SAR system working together and form a large virtual satellite to finish more tasks and reduce the risk. There are several channels in GEO SAR formation, which can be utilized to detect the moving target. Space-Time Adaptive Processing(STAP) suppresses clutter in space-time plane to accomplish moving target detection in the background of strong clutter. According to the traditional STAP algorithm, this paper proposes a method of moving target detection based on the GEO SAR formation and analyzes the performance through the simulation. |
