中远程空空导弹多机协同中制导交接方法

Method of guidance handover in midcourse guidance phase of air-to-air missile about cooperative multi-platform

针对在同类型空中平台协同作战条件下,中远程空空导弹中制导权在移交过程中存在信息突变的问题,提出采用"虚拟目标"法对突变信息进行渐近处理,使虚拟目标逐步向真实目标运动,最终"导弹—虚拟目标"视线角与"导弹—真实目标"视线角重合,则中制导权移交结束;提出三种不同的中制导权交接律,在目标不机动/机动两种情形下,通过仿真分析不同模式下的交接律对空空导弹过载的影响。仿真结果证实适当平缓地进行制导权移交能将突变信息转化为接近于目标机动形成的、导弹自身能够处理的突变信息。避免了直接交接使导弹过载突变到非正常值的情况,使中制导交接能够平稳进行。

Aiming at solving the problem of target information break in the process of handing over the guidance of Mid-Long range air-to-air missile between the same kinds of aircrafts in cooperative air combat,a method of ＂virtual target＂ was proposed：the virtual target approached the real target gradually,when the aspect angle of missile-virtual target and the missile-real target matched,and the process of handing over the guidance was over.Three different modes of approaching movement was proposed,and the affection on the over loading of air-to-air missile was analyzed through simulation of the situation of the target in the process of maneuvering and not maneuvering.The simulation results showed that handing over the guidance appropriately and moderately can transform the break information which is unmanageable into the break information which is manageable,and can avoid the information breaking into improper value if the guidance is handed over roughly.
