Abstract:

It is very important to research early warning of a single satellite, because it is a necessary process and an important part of the early warning system. The early warning of a single satellite belongs to the condition of incomplete surveys and needs to estimate the missile trajectory as well as the point of descent parameter based on early warning database. Considering the missile dynamic characteristic, a method suitable for early warning of a single satellite is established to solve the deficiency existing in the method with ballistic trajectory as characteristics. Finally, the simulation comparation is carried on, and the  results show that the proposed method is confirmed more reliability and feasibility.
