Tracking Midcourse Target and Error Analysis
摘要
Abstract
In order to improve the convergence rate and precision of midcourse target tracking, an algorithm based on IMM ( Interaction Multiple Model )-EKF ( Extended Kalman Filter ) was proposed. Based on the variation characteristic of acceleration of midcourse target,three-dimensional target-motion-model and measurements model were built by using velocity measured-value. A comparative analysis between IMM-EKF and traditional EKF was carried out. The simulation results show that IMM-EKF algorithm can improve the convergence rate of midcourse target tracking,and the tracking precision can also be improved by using velocity measured-value. The proposed filtering method has better tracking per-formance in midocurse,and it is effective.关键词
