| 摘 要： | 天基预警系统是国家战略预警系统的重要组成部分,而单星探测预警是天基预警系统发展必经历程和重要环节,传统方法基于标准弹道模板先验信息支持,但标准弹道模板信息难以获取,无法实际应用.本文主要讨论在没有标准弹道模板先验信息支持的情况下,单颗预警卫星能否及早给出导弹射向估计的问题.通过建立弹道导弹飞行的动量模型和弹道平面切割模型,本文提出了基于单颗预警卫星观测视线对来袭导弹射向的估计算法,回答了单颗预警卫星观测情况下如何给出射向信息的问题,仿真计算结果表明,本文方法对于引导地基预警系统具有较高的精度和实用价值,本文方法亦可应用于各类单站无源探测(预警雷达,中低轨、大椭圆预警卫星等)的方位信息估计与空间目标机动的识别等问题.

| Abstract: | The early warning of single satellite is a necessary process and an important part of the early warning system.As forepart warning,it is very important to give trajectory course information early to radar system for putting a tail on the missile.In this paper,based on the missile momentum equation,taking into account the basic physics' restrictions in missile's manufacture and flight,a new method is established to obtain the trajectory course by early warning of single geosynchronous satellite,without prior... |
