摘要
针对末制导阶段寻的导引头无法在多目标环境下稳定跟踪单个目标造成最终脱靶的问题,分析了多目标干扰对导引头角度跟踪的影响;基于正交多载波技术提出了在同一时刻利用不同探测频点获得多个角度误差输出方程,提取出多目标未知参量,实现对单个目标精确跟踪的方法;通过仿真分析验证了该方法合理可行,分析成果可应用于制导系统,达到改善导引头末制导跟踪过程中跟踪精度的效果。
To solve the problem caused by multi-target interference in the terminal guidance phase,which affects stable target tracking and results in the final miss,the influence of multi-target interference on the seeker’s angle tracking is analyzed,and multi-target interference compensation methodology using multiple output angle error equations with different detection frequencies at single sensing period to extract the unknown parameters of multi-target interference based on the orthogonal multicarrier technique is proposed in this paper.The method is verified reasonable and feasible through the simulation analysis,and the analysis result can be applied to improve the tracking precision of the seeker’s terminal guidance phase.
