摘要
基于e/i矢量表示的编队卫星相对运动学方程,根据合成孔径雷达干涉(InSAR)卫星成像过程中测量基线长度、安全防撞等约束,给出了可实现全球测量的高、低纬度编队构形优化设计方法。仿真结果与理论分析相符。该编队构形方法充分考虑了InSAR卫星的成像特性及编队卫星的构形长期安全性约束,可减少编队卫星构形保持次数,为InSAR卫星编队飞行控制和工程实践提供依据。
Based on the equations of relative motion which was described by an eccentricity/inclination vector, a new optimal contrivance of satellite formation design including high and low latitude mapping mission was proposed for global observation according to the restrictions of baselines, collision avoidance during InSAR satellite imaging in this paper. The simulation results were consistent with the theory analysis. In as much as the consideration of restrictions comprising characteristics of InSAR satellite imaging and formation safety during the process of formation design, the formation parameters gained by this method could satisfy the demand of baselines perfectly and minimize the collision hazard and formation keeping frequency.
