摘　　要：近年来中国在轨卫星数量与日俱增,航天地面测控资源日益紧张,地面站现有的球面共形相控阵存在极大的阵面资源浪费,针对地面测控站阵面波束资源的调度分配可以有效利用现有阵面资源,为日后数量更庞大的航天测控任务需求增加资源裕度,为此需要对中国在轨卫星相对阵面的分布情况进行可见性分析;设计了一种基于STK与Matlab互联的仿真计算方法,该方法利用中国在轨卫星实时TLE数据,通过Matlab对STK控制仿真卫星相对地面站的分布及可见性,并把仿真数据存入Matlab,进一步仿真卫星对子阵的可见性,统计对各子阵的可见性结果;仿真结果得出了球面阵上各子阵在全天时刻的可见卫星数量以及资源较为紧张的子阵分布,该结果可以为球面共形相控阵波束资源调度设计提供参考。In recent years,with the number increasement of China's in orbit satellites,space ground TT&C resources have become increasingly scarce.Existing spherical conformal phased array at ground station has a huge waste of array resources.The scheduling and allocation of array beam resources at ground TT&C station can effectively use existing array resources,the resource margin for a larger number of space TT&C tasks is increased in the future,therefore,it is necessary to conduct visibility analysis on the distribution of China's orbiting satellites relative to the array;A simulation calculation method based on the interconnection of satellite tool kit(STK)and Matlab software is designed.This method uses the real-time TLE data of China's orbiting satellites,analyzes the distribution and visibility of satellites relative to ground stations through the interconnection of STK and Matlab simulation,and stores the simulation data in the Matlab platform to further simulate the visibility of satellites to subarrays,and counts the visibility results of each subarray;The simulation results show that the number of visible satellites of each subarray on the spherical array at all times of the day and the distribution of subarrays with relatively tight resources are obtained,The results can provide a reference for the beam resource scheduling design of spherical conformal phased array.
