针对无导引头导弹在采用现有制导律时定位误差会产生较大脱靶量的问题,通过双领弹的领弹-从弹协同架构,设计了一种协同定位与制导策略,以实现无导引头导弹对静止目标的精确命中。基于扩展卡尔曼滤波,提出了一种无导引头导弹的协同定位方法。该协同定位方法与比例导引结合时存在终止时刻过载指令过大问题,因此设计一种新型变系数比例导引律,分析了变系数比例导引律的制导系数对脱靶量、终止时刻过载与最大过载的影响。仿真结果表明:采用所提出的协同定位方法可减小具有定位误差的无导引头导弹脱靶量,而采用变系数比例导引律可避免终止时刻过载指令过大。 |

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. |
