摘要 研究星载SAR干涉测量中伴随卫星编队构形保持与姿态控制的协同问题。首先,简介主SAR卫星与伴随卫星编队所构成干涉测量系统的工作原理,当主SAR卫星施加偏航导引补偿多普勒频移时,为实现波束指向同步,伴随编队需进行构形与姿态的协同控制。给出协同控制框架结构图,通过设置轨道协同规划器与姿态协同规划器明确了解决方案;进而从构形规划、姿态规划、构形与姿态协同控制三方面具体地阐述伴随编队的协同控制技术。最后对构形保持、姿态规划和姿态控制进行数值仿真,结果表明伴随编队的协同控制满足波束指向同步要求,所提出的协同控制方案具有可行性。 The coordination problem of formation maintenance and attitude control of concomitant satellite formation in spaceborne InSAR system was studied. First, the principle of InSAR system was introduced. When SAR satellite compensates Doppler Shift with yaw steering, for beam pointing synchronization, formation maintenance and attitude control of concomitant satellite formation should be coordinated. The coordination architecture with an orbit coordinator and attitude coordinator was proposed, which illustrated the approach to the coordination problem. Then, formation planning methods, attitude planning methods and laws of coordination control were concretely studied. Last, numerical simulations indicate the architecture of coordination control is feasible.
