平台式导引头跟踪回路对制导系统的影响

针对应用速率陀螺的伺服平台式导引头跟踪回路的导弹制导控制系统特点,分析了伺服平台式导引头跟踪系统的稳定回路增益变化、速率陀螺的加速度敏感特性、弹体的运动耦合以及导引头天线罩斜率等不确定性对导弹制导控制系统的稳定性以及制导回路最终脱靶量的影响。对上述的影响因素分别进行了理论推导与数学仿真,仿真结果表明,上述不确定性对制导系统有重要的影响。该研究对平台导引头跟踪回路系统的工程实现有一定的理论指导和参考意义。

Influence Analysis of Tracking Seeker Component Imperfections to High Off-boresight Launch Missile

Practical design consideration for missile tracking seeker is presented,which is gimbaled with respect to the missile to allow target acquisition and tracking.In this paper,tracking seeker component imperfections,such as stabilization loop gain variety,gyro acceleration sensitivity,coupling of the body movement and radome slope,are discussed.The stability issues and miss distance caused by these imperfections are analyzed by using simulation.This paper has theory guidance and reference significance to the e...
