The Method of Trajectory and Attitude Data Generation for Space Target
School of Astronautics, Harbin Institute of Technology, Harbin 150001, China
To solve the problem of space targets' trajectory and attitude data generation in system simulation, the characteristics of various types of ballistic missiles and their midcourse targets are analyzed deeply. The baseline ballistic is divided into four types and design methods are given respectively, based on which multiple independently reentry vehicle (MIRV) ballistic design method is established. This method doesn't need preparations and simplifies the system simulation. In addition, an attitude data generation method according to micro-motion characteristic quantity is proposed in order to simulate midcourse target's micro-motion. This method doesn't require numerical integral and speeds up the computation. Simulation results show that four types of baseline trajectory and MIRV trajectory that can accurately hit the target are generated in ten seconds. In addition, the attitude data can reflect the micro-motion characteristic, and the time for data generation is short. This method can meet the requirements of system simulation.
