摘要
讨论了分布式卫星系统中卫星姿态变化、地球自转、卫星环绕等因素,及对小卫星间基线测量引起的误差。分析了卫星姿态变化带来的基线误差对干涉SAR测高的影响。理论分析和仿真结果表明,当姿态误差为0.1时,将导致0.1 m的基线误差和20.42 m的干涉SAR测高误差。
The satellites attitude, the earth rotation and the cluster-satellite rotation will affect the baseline between two micro-satellite in the cluster satellite system . In this paper, the height-measure error influenced by satellites attitude will be analyzed especially. Theoretical analysis and simulation results demonstrate that 0.1 attitude error will bring on 0.1 m baseline error and 20.42 m height-measure error.
