摘要
针对程序控制导弹转弯方式的不足,提出了基于波束指令控制的空空导弹越肩发射方式。首先介绍了波束指令引导律;然后对引导段载机和导弹相对运动进行建模,求出导弹在三维空间内的弹道;推导出燃气舵导弹动力学方程和波束指令引导律与导弹控制机构的关系;最后对所推导的结论进行仿真验证。仿真结果表明了波束指令变化规律、导弹运动轨迹、法向过载变化规律、攻角变化规律和舵偏角的变化规律是一致对应的。
Taking the shortcoming of programming control in missile＇s wheeling into consideration, a new method of OTS based on beam-instruction is put forward. The guidance law of beam-instruction is described, then mathematic model of mutual movement for fighter and missile at inductive stage is founded, the missile＇s moving track in three-dimensional space is calculated. The relation between beam-instruction and missile＇s control system is deduced. At last the referenced conclusions above all are simutated and verified. The results show that the beam-instruction is corresponding to the variety of beam-instruction, missile＇s vertical over-loading, attacking angle and the rudder deflection.
