摘要
单星探测预警是天基预警系统发展的必然经历过程和重要组成部分,单星探测预警属于不完备测量,需要先验信息的支持才能估计弹道以及进行相应的预警,因此如何构建预警信息库就尤为重要。首先分析了一种弹道导弹的本质特征,并在此基础上建立了提取弹道特征信息的算法,从而使单星预警成为可能,仿真算例验证了该方法的可行性。
The early warning of a single satellite is a necessary process and an important part of the early warning system. As single satellite belongs to the condition of incomplete surveys, the missile trajectory as well as the warning information is estimated based on early warning database. So it is very important to construct early waming database. Firstly, the missile characteristic of the essence was analyzed, and the method was established to obtain ballistic trajectory in order to make early warning of a single satellite possible. Therefore, the corresponding simulation computation has been carried on and shows the method feasible.
