An orbit optimization method for low earth orbit electronic reconnaissance constellation
低轨星座是近年来航天领域的热点方向,在通信、导航、侦察等领域展现诸多优势.本文以低轨巨型星座搭载电子侦察载荷为研究对象,在特定星座构型和轨道高度约束条件下,研究了基于最小化卫星总数和最优化定位性能(CRLB)的低轨电子侦察星座轨道优化方法.通过 STK/Matlab 联合仿真,优化后的星座方案在卫星总数减少 235颗、轨道面数缩减 6 个的情况下,其辐射源定位性能较星链构型提升达 50%.因此通过低轨星座优化设计,可在显著降低系统资源消耗的同时,实现对特定区域的高效无源实时监测.
Low-orbit constellation is a hot spot in the field of aerospace in recent years,which shows many advantages in the fields of communication,navigation,reconnaissance and so on.In this paper,the orbit optimization method of LEO electron-ic reconnaissance constellation based on minimizing the total number of satellites and optimizing the positioning performance(CRLB)is studied under the constraints of specific constellation configuration and orbit height.Through STK/Matlab co-simulation,the optimized constellation scheme improves the positioning performance of the radiation source by 50%com-pared with the star chain configuration when the total number of satellites is reduced by 235 and the number of orbital sur-faces is reduced by 6.Therefore,through the optimization design of LEO constellation,the efficient passive real-time moni-toring of specific areas can be realized while significantly reducing the system resource consumption.
