摘要
针对舰空导弹采用双模复合制导导引头的特点,介绍了旋转式相位干涉仪的测角原理和红外玫瑰扫描跟踪目标的实现方法;在分析舰空导弹交班流程的基础上,对被动微波/红外制导交班误差进行了分类和计算,分析求解出导弹交班总误差;通过实例仿真,讨论了各误差源对交班误差的影响。仿真结果可为舰空导弹复合制导交班及导引头设计提供参考。
According to the characteristics of dual-mode combined guidance seeker of ship-to-air missile,the angle measuring principle of rotating phase interferometer and realization method of target tracking in infrared rosette scanning are introduced.Based on analyzing the hand-over process of ship-to-air missile,the hand-over error of passive microwave/infrared guidance is classified and calculated,total hand-over error of missile is analyzed and solved.Through example simulation,the influence of each error source on hand-over is discussed.Simulation result can provide reference for the study of hand-over process and seeker design for the combined guidance of ship-to-air missile.
