摘　　要：无源测向技术是反辐射导弹关键技术之一,为解决导引设备复杂和反辐射导弹空间有限的矛盾,将一种4基线天线组合的单脉冲体制导引头干涉仪无源测向系统用于反辐射导弹导引装置中。研究了如何使4基线天线交叉安装组合方式得到更高的导弹导引头测角精度和测角范围。针对反辐射导弹"Ⅹ"字形舵面控制角度与导弹头角度测量系统的不一致性,通过对目标测向模型进行改进,研究了在干涉仪测量坐标系和弹体控制坐标系之间,目标方位角度、俯仰角度的解耦关系;进而为控制导弹"Ⅹ"字形舵面提供了依据。Passive direction finding is one of the critical technologies for Anti-Radiation Missile （ARM）. The homing equipment is complex and the inside space of ARM is very limited. To solve the contradiction, a 4 baseline antennas angle interferometer was used in ARM homing system. This interferometer is a passive direction finding system adopting monopulse technique. The installation and combination of the 4 baseline antennas were studied to improve angle precision and angle-searching area of this interferometer. For ＂ X＂ form rudder of ARM, controlling angles are different from measuring angles of interferometer. Based on improvement to target direction finding model, the decoupling relations of azimuth or pitch of target between measurement coordinate system and projectile control coordinate system were studied, which supplies a reference for missile controlling.
