摘要
提出了一种基于双光束扫描的卫星光通信捕获技术。使用两束信标光同时对目标卫星所在的不确定区进行扫描,目标卫星在探测到信标光后利用无线电信号向主动方卫星发送应答信号。通过对应答信号所携带信息的计算分析,最终确定目标卫星所在位置,实现捕获。数值仿真计算表明,该方法比传统方法扫描效率提高90%左右。
A satellite communication capturing technology based on dual-beam scanning is put forward.Two beacons are used in this technology to scan the uncertain region where the target satellite is.After detecting the beacons,the satellite sends answering signals to the initiator with radio wave.The target satellite is finally located and captured by the initiator by analyzing the information transmitted in the answering signals.Numerical simulations show that this method improves the efficiency by 90% compared with the conventional methods.
