摘要
捷联导引头是空空导弹导引头的一个重要发展方向,由于其天线与弹体固连,隔离弹体姿态扰动对导引头测量信息的影响是其急需解决的关键技术之一。本文在分析捷联导引头特点的基础上,提出了一种角速度补偿型捷联去耦算法,并利用导引头波束指向在惯性空间变化率为零的特点,推导出三维空间中捷联去耦算法的实现形式,最后通过计算机仿真验证了算法的有效性。
Strapdown seeker is a development tendency of the air-to-air missile seeker. Because the antenna is fixed with the missile body, how to isolate the effect of attitude disturbance on measurement information of seeker is one of its key technologies. This paper presents a decoupling algorithm of angular velocity compensating on the basis of analyzing the characteristics of strapdown seeker. By the invariance principle of seeker beam direction in the inertial space, the decoupling algorithm in three-dimensional space is derived. The algorithmic validity is finally proved by computer simulation.
