预警卫星对弹道导弹发射点战术参数的估计

摘要

In order to evaluate the tactical parameters of ballistic missile launch point,it is needed that locating missile using detect information of early warning satellites.Based on the theory of double satellites location and ballistic trajectory,the transformation model from ECF_VVLH coordinate to ECF coordinate,double satellites location model and tactical parameter evaluation models are provided.Using STK and STSS,the tactical parameters of launch point are simulated.Simulation result verifies the efficiency of the algorithm,and the superiority of STSS.%为了对导弹发射点战术参数进行准确估计,需要根据预警卫星的探测信息对导弹进行定位。基于双星定位原理及导弹弹道特性,给出了从测量坐标系到地球固定坐标系的转换模型、发射点时刻以及发射点位置估计模型,并利用仿真工具STK,结合美国新一代导弹预警卫星系统——空间跟踪与监视系统（STSS）,对发射点战术参数的估计进行了仿真。仿真结果表明了该算法的有效性,并说明STSS与传统预警卫星相比,具有更好的探测预警能力。
