摘要
多武器平台同时探测、处理机动目标信息,一定程度上可以提高目标的跟踪精度,特别是对于多导弹协同作战而言,协同跟踪目标即可以为作战系统提供全面的协同控制情报,也可以为每枚导弹提供精确的制导信息.论文基于交互多模与几何关系思想,设计了多导弹协同跟踪目标算法.首先,建立了目标运动学模型,给出了多导弹和目标之间的几何关系,并以此为基础,建立了多导弹协同跟踪目标模型;其次,基于交互多模思想,将多导弹获取的目标信息进行交互,通过协同滤波算法计算出目标滤波状态值;最后,对协同滤波算法进行仿真验证.研究表明:相对于信息不共享的情况,多导弹协同跟踪目标能够取得更好的跟踪效果,对多导弹协同作战具有重要的参考意义.
Multiple weapon platforms can detect and deal with the target information at the same time, so the guidance precision can be greatly advanced, especially in the multiple missile cooperative engagement, cooperative-tracking will provide more target information for the engagement system, also the single missile can be obtained the accurate guidance information. Based on the idea of information sharing and geometric relation among missiles, the new algorithm of the multiple missiles cooperative tracking target is derived. Firstly~ the model of target kinematic was built, based on the geometric relation between the missiles and the target, the measurement model of the target tracking by multiple missiles was given. Secondly, based on the idea of interacting multiple model algorithm, the target information measured by different missile was fused, so the target state was calculated, also the cooperative filter algorithm step was given. At last, the simulation results shown that, compared to the information non-sharing mode, the multiple missiles cooperative tracking target has a better performance, this will have great meaning in the multiple missiles cooperative engagement.
