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 InSAR formation satellites, the effects of space perturbations such as the shape of the earth, the atmospheric resistance, the third body gravity and the solar pressure on the satellite orbit are analyzed. The influence of space perturbations on formation configuration is also discussed. The results show that the perturbation of the earth shape and the perturbation of the air resistance are the main perturbation factors that cause the formation change of InSAR formation. Under the action of these perturbation forces, the changes of formation configuration are mainly the cumulative changes along the track and the formation ellipse The changes of formation orientation over time are given. Research provides a reference for the formation control.
