Abstract

In this paper, we studied the problem of estimating trajectory parameters of ballistic missile (BM) such as the first detected point and impact position, in space early warning of a single low orbit satellite, and provided corresponding precision analysis. The main idea is that through matching the observation trajectory data to the trajectory equation of free flight phase, first detected point and the main trajectory is determined. Simulation results review that those algorithms in this paper is efficient.
