新的导弹协同定位技术

导弹协同作战的关键技术之一是导弹的精确定位技术,针对在体系对抗条件下,如何提高导弹集群的导航定位精度问题,构建了以弹载数据链和惯导系统为核心的协同定位系统,提出了一种基于相互测距信息的导弹协同定位方法.该方法使用加权秩亏自由网平差的方法来估计导弹集群的惯导系统定位误差.仿真表明:该方法可以有效地延缓惯导位置误差的发散速度和提高惯导定位精度,随着导弹数量的增多,惯导定位精度不断提高,当导弹数量大于4时,惯导定位精度将提高2倍以上.

New techneque for multi-missile cooperative localization

One of the key technologies in multi-missile cooperative combat(MCC) is the missile precision positioning technology.In the environment of system-of-systems combat,multi-missile cooperative localization(MCL) based on mutual rangings was proposed to improve the inertial positioning accuracy of the missile community.The cooperative localization system,which is mainly composed of the missile-borne data link and inertial navigation system(INS),was designed and the ranging scheme of the data link as well as the time synchronization problem was analyzed.The weighted rank-defect network adjustment algorithm was applied to estimate the inertial positioning errors.Simulation results show that the method slows down the divergence speed of positioning errors and improves the positioning precision effectively.The positioning precision comes higher with the increase of missiles and it is more than 2 times of the original level when the number of missiles is more than 4.
