两种卡尔曼滤波模型在修正弹弹道数据处理中的应用比较
Application Comparision of Two Kalman Filtering Models Used in Trajectory Data Processing of Correction Projectile
摘要
Abstract
To estimate the uncontrolled trajectory of trajectory correction projectile accurately and rapidly,so as to control the flight path and improve the firing dispersion, both of the dynamic motion model(DMM) and point-mass trajectory model(PMTM) were applied to the estimation of flight states for trajectory correction projectile based on GPS and Kalman filtering method. The simulation results indicate that the filtering estimation precision and convergence rate of PMTM are better than those of DMM, but the precision of system model parameters is strictly required for PMTM,and the adaptability of PMTM for the model parameters and variation of process parameters is worse than that of DMM.关键词
