天基预警卫星弹道预报能力仿真分析

摘要

Space-based early warning satellites can forecast the errors of ballistic position and velocity which is the important component of guidance information and directly influence search performance of long-range early warning radar and tracking and guiding radar.According to give information about the Line-of-Sight (LOS) angular errors of the satellites and their ballistic target empirical data,ballistic prediction error estimation modeland compute prediction error bands is designed.The simulations show that horizontal and vertical plane prediction error bands of viewing satellites can be obtained by analyzing observation errors covariance for ideal trajectory target.%天基预警卫星对导弹位置和速度的预测误差是引导信息中的重要组成部分,直接影响到远程预警雷达和跟踪制导雷达的搜索性能.根据天基预警卫星视线角误差和导弹目标经验数据,设计导弹预报误差估计模型,计算预报误差带半径.仿真结果表明:通过对理想弹道目标进行观测误差协方差分析,可以获得预警卫星观测的水平及垂直平面预测误差带.
