摘　　要：配置侧窗导引头能有效提升导弹红外成像跟踪探测范围,在配置侧窗导引头的防空导弹应用比例导引时,比例导引在侧窗探测条件下的适用范围及各因素对其制导特性的影响具有重要的工程意义。根据所建立的制导模型,仿真研究了相关因素对配置侧窗导引头的防空导弹应用比例导引时红外成像跟踪探测范围的影响,仿真结果表明:调节比例导引的导航比、增大导弹初始速度方向与视线方向间的夹角及在导弹和目标速度比不变的情况下增大速度值均能增大探测范围。表明比例导引对配置侧窗导引头的防空导弹红外成像跟踪探测具有较好的效果。The method of configuring the seeker in the side window can effectively improve the missile＇s infrared imaging detection range. Studying the application range of proportional navigation under side window detection and the impact on guidance characteristics caused by various factors has important engineering meaning, when the antiaircraft missile with its seeker in side window adopts proportional navigation. Based on the established guidance model, the paper discussed the influence of the infrared imaging detection range under side window detection for the missile caused by factors associated with proportional navigation. The results show that the application range of proportional navigation can be enlarged by regulating navigation ratio, increasing the absolute value of angle between the direction of initial missile velocity and line of sight, or increasing the speed of missile and target with the speed ratio unchanged. The conclusion is that the proportional navigation has a good performance on antiaircraft missiles＇ infrared imaging detection with side window seekers.
