SBIRS-High对助推段导弹的探测和跟踪能力研究

Study on the detecting and tracking ability of missile in boost phase in the space based infrared satellite constellation of high altitude

依据天基红外高轨系统的特点和任务,分析了地球静止轨道和大椭圆极地轨道红外卫星系统的对地覆盖和监视性能,建立了大椭圆轨道系统的跟踪定位算法。为提高系统的跟踪性能,对视线交会定位原理所得到的结果作了进一步的卡尔曼滤波处理,进而获得了导弹速度估计。仿真结果表明,天基红外高轨系统可对全球的目标助推段实施监视,并能及时提供有效的导弹运动参数信息。

According to the missions and characteristics of the space based infrared satellite constellation of high altitude（SBIRS-High）,the coverage ability and surveillance capability of Geosynchronous Earth Orbits（GEO） and Highly Elliptical Earth Orbits（HEO） satellites were analyzed.The tracking and locating algorithm of the HEO system was given especially.To improve the capability of the system,The results of Bearing-only location theory were used in the Kalman-Singer filter for further computing,which could provide the velocity estimation of missile in boost phase.Simulation results show that SBIRS-High could surveille missiles in boost phase of the whole global and offer the movement parameter of targets very well.
