针对大离轴角发射的红外型导弹采用平台式导引头跟踪回路的特点,分析了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以及弹体的运动耦合这三个不确定性对导弹制导控制系统的稳定性以及最终脱靶量的影响。通过仿真表明,这三个不确定性对制导系统有重要的影响。文中研究对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。

Practical design considerations for a high off-boresight launch missile tracking seeker is presented, which is gimbaled with respect to the missile to allow target acquisition and tracking. In this paper, three tracking seeker component imperfections, such as stabilization loop gain variety, gyro acceleration sensitivity and coupling of the body movement, are discussed. The stability issues and miss distance caused by these imperfections are analyzed by using simulation. This paper has theory reference significance to the engineering design of tracking seeker system.
