基于领弹-从弹架构的无导引头导弹协同定位与制导方法

A novel cooperative localization and guidance approach based on the leader-follower framework with two leaders is proposed to allow the seeker-less missile to hit a stationary target accurately. A cooperative localization method for seeker-less missile is designed based on the extended Kalman filter to enhance the localization accuracy. To address the issue that a large terminal acceleration command is required for the proportional navigation guidance (PNG) law combined with the proposed localization method, a novel PNG law with time-varying navigation gain is presented. The impacts of the guidance parameters on miss distance, terminal acceleration and maximum acceleration are demonstrated through si-mulation. Simulated results show that the large miss distance due to the localization error of seeker-less missile could be reduced by the proposed cooperative localization method, and the large terminal acceleration command could be avoided by PNG law with time-varying navigation gain.
