针对干涉合成孔径雷达（InSAR）编队卫星的特点,分析了地球形状、大气阻力、第三体引力和太阳光压等空间摄动力对卫星轨道的影响,并仿真讨论其对编队构型的影响。结果表明：地球形状摄动和大气阻力摄动是引起InSAR编队构型变化的主要摄动因素,在这些摄动力的作用下,编队构型的变化主要是沿航迹向的累积变化和编队椭圆的空间指向变化两种,并给出了编队构型随时间的变化量。研究为编队保持控制提供了参考。

According to the characteristics of intermetri synthetic aperture radar （InSAR）, the influences of the earth space perturbations such as the earth shape, atmosphere drag, the third-body graritational and solar radiation pressure on the orbit of the satellite were analyzed in this paper. And the influences on the formation flying configuration were discussed by the simulation. The results showed that the earth non-spherical gravitational and atmosphere drag perturbation were the main factors which affect the formation configuration. And the formation flying configuration＇s change mainly were the cumulated change on the satellite track direction and the formation flying eclipse direction change. The variation of formation flying framework with time was calculated. The study was valuable to the formation flying maintenance control.
