导引头指向角误差研究

提出了以理论弹目线为中心的扫描方式，该方式能减小导引头扫描角度范围和扫描周期，降低了导引头设计技术指标要求；建立了以理论弹目线为中心的导引头指向角模型，并对其误差进行了分析；采用Monte- Carlo法对导引头指向角误差进行了仿真计算。结果表明，以理论弹目线为中心的扫描方式扫描角度范围减小2a，a大小与目标横向机动速度、导弹射程和采用的中制导律有关。研究结果可以对同类的自寻的导弹工程研制起借鉴作用。

Study on Pointing Error of Seeker

The target scanning pattern taking theoretical line of sight as center was proposed, wmch can decrease scanning angle scope and period, reduce technical index requirement for the seeker; the pointing model of the seeker was established, its error was analyzed; the error was simulated by Monte-Carlo method. The simulated results show that the scanning angle scope can decrease 2a, wich value is related to target lateral maneuver speed, missile range and adopted medium guidance law. The studied results can play a role in reference for homing missile engineering research and devel-opment.
