ECEF 坐标系弹道导弹跟踪研究
A Study on Ballistic Missile Tracking in ECEF Coordinate System
摘要
Abstract
Aiming at the problem that single model tracking algorithm can not track the ballistic missile accurately , an interacting multiple model ( IMM) algorithm is proposed in Earth-centered Earth-fixed coordinate for continuously tracking the missile for all the flight stage .According to the force condition in different stages of trajectory , the corresponding tracking model is established . The axial force of target almost keep constant in boost phase , the constant axis force model is adopted;coast and reentry phase use the passive phase tracking model to track the missile .Both the models use the cubature Kalman filter algorithm to filter .In view of the problem that a bias is caused in the mixing stage of this IMM algorithm , an unbiased mixing method is adopted .The simulation results verify the superiority of the algorithm .关键词
