摘要
以天基监视为背景,依据几何学原理和矢量计算工具,主要研究了双星相对运动模型。一方面,突破力学求解方式,采用一种区别于传统轨道根数的卫星轨道生成规则,可清晰直观地描述卫星轨道;另一方面,结合光电跟踪系统,研究了双星运动过程中的相对方向变化。通过对异面太阳同步圆轨和共面地球同步圆轨双星相对运动模型的仿真计算,获得了卫星轨道、相对距离、方位角、俯仰角、方位角速率、俯仰角速率的变化结果,分析结果证明了此方法的合理性,可为天基监视中的工作区域选择、卫星轨道设计、监视系统设计和捕获跟踪瞄准控制系统设计等物理问题和关键技术提供定性和半定量参考。
Abstract
Relative movement model of two satellites was mainly researched in space-based surveillance by geometry principle and vector calculation tool. On one hand, satellite orbit can be described clearly using a kind of producing rule of satellite orbit that is different of orbit elements and solving mechanics equation. On the other hand, relative directions of two satellites in the movement are researched by combining opto-electrical tracking system. Corresponding results of satellite orbit, relative distance, azimuth angle, pitching angle, azimuth angle velocity and pitching angle velocity were achieved after computing relative movement of two sun synchronous orbit satellites on different planes and two geosynchronous orbit satellites on the same planes. Analysis results show that this method is reasonable and provides qualitative and semi-quantitative reference for some physics question and key technologies in space-based surveillance such as design of satellite orbit, selection of work region, design of surveillance system and acquisition tracking and pointing control system.
