地球静止轨道预警卫星可以探测到处于助推段飞行的弹道导弹，建立相应的预警卫星星座可以实现对全球范围内的弹道导弹进行探测和监视，随着预警卫星技术的不断发展和反导预警的需求，星座组网将成为预警卫星重要的作战方式。为此，对双GEO预警卫星的覆盖范围进行了分析，通过构建双星探测模型，表明了双星覆盖范围主要由双星间的夹角与星载探测器的视场决定；在不同探测器视场情况下，对双星覆盖范围随双星间夹角变化情况进行了仿真，结合预警卫星的探测任务区域，得到双星探测条件下夹角的最优选取，可为星座组网提供参考。

As the Geo-stationary earth orbit (GEO) early warning satellite could detect the ballistic missiles in its boost phase flight, the establishment of relevant early warning satellites constellation may realize the global detection and monitoring of the ballistic missiles. With the continuous development of early warning satellite technology and the demand of anti-missile early warning, the constellation networking will become an important operating mode of early warning satellites. Therefore, this paper analyzes the coverage area of double GEO early warning satellites. By constructing the model, it shows that the coverage area of double satellites is mainly determined by the included angle between double satellites and the satellite-borne detector’s field of view. Under the circumstance of the detector’s field of view being determined, the relation between the coverage area and included angle between double satellites is simulated, and the optimum selection of the included angle in the case of double satellite detection can be achieved by combining with the flight parameters of the ballistic missiles, which can provide a reference for the constellation networking.
