摘要
为了提高潜射弹道导弹早期预警能力,设计了一种低轨道Walker卫星星座.该星座利用低轨卫星对导弹预警卫星系统进行补充,实现对应急任务的快速响应.以预警探测系统的连续覆盖能力为指标,利用STK软件对该设计进行了建模仿真,并就卫星轨道参数、星座构型和覆盖性能等方面进行了详细分析.仿真分析结果表明,该星座可对我国周边局部威胁海域实现97%以上的连续覆盖,并对该区域北纬26°以下的部分实现严格连续覆盖.
In order to enhance the early warning capability of submarine launched ballistic missile （SLBM）, this paper designs an LEO Walker satellite constellation, which backs up the missile early-warning satellite system by using the LEO satellite, implementing the fast response of emergency tasks. By taking the continuous coverage capability of the early-warning detection system as an index, the corresponding modeling and simulation are performed on this design, using STK software. And the detailed analysis is done in terms of the parameters of satellite orbit, configurations of constellation, coverage performance and others. Simulation analytic results show that the constellation designed can achieve more than 97% continuous coverage for local threatened sea area around our country, and realize a strict continuous coverage for those parts below 26° of north latitude areas.
