异构预警卫星星座设计与分析

Design and Analysis of Non-isomorphic Early Warning Satellites Constellation

针对北半球预警卫星的应用背景和设计要求，结合椭圆轨道的覆盖特点，提出了一种由中椭圆轨道卫星和赤道圆轨道卫星组成的异构预警卫星星座设计方案，并对该预警星座的预警性能进行了仿真分析。仿真结果表明，这种异构星座构形具有很好的区域覆盖性能。

According to the requirement of application and design of early warning satellite covering with the northern hemisphere of earth, the project of non-isomorphic early warning satellites constellation is put forward using coverage characteristics of ellipse orbit, which is composed of ellipse orbit satellites and equator circle orbit satellites. The early warning performance of the constellation is analyzed by simulation. And the results of simulation show the non-isomorphic constellation has fine region coverage performance.
