多颗低轨卫星探测导弹的时间窗口可视化方法

摘要

针对多颗低轨光电侦察卫星在预定弹道轨迹上空的探测时间重复计算且计算结果不直观的问题,提出了基于"跑道型"探测窗口区的卫星探测时间窗口可视化方法.该方法将预定弹道轨迹地面投影线作为低轨光电侦察卫星的探测目标,建立"跑道型"探测窗口区模型,将星下点轨迹在探测窗口区的线段长度与探测时间相对应,实现了卫星探测时间窗口的可视化.仿真验证表明,该方法的计算值与观测值之间误差在百分之一秒数量级,同时能够直观形象地显示从不同轨道方向过顶的多颗卫星的探测时间窗口,避免了多颗卫星探测时间窗口的重复计算.%Aiming at the problem of repeated calculation and the intuitive calculation result on the time windows of multiple low orbit satellites detecting predetermined trajectory,a visualization method for the time window based on the"runway" detection window was proposed.The predetermined trajectory projection on the ground line as the target of low orbit photoelectric reconnaissance satellite ,the model of"runway"detection window ar-ea was established.And the visualization of the time window of the satellite detection was realized by corre-sponding star locus in the detection window area of line length and detection time.Simulation results showed that the error between the calculated value and the observed value was one percent seconds,at the same time,the method was able to display the detection time window of multi satellites which over the top in different orbit a-voided the repeated calculation of the time window of the multi satellite detection.
