多径条件下机载箔条质心干扰研究

Research on Airborne Chaff Centroid Jamming in Multipath Environment

箔条质心干扰是载机应对来袭导弹的一种重要的自卫手段,对于保护载机免受导弹打击具有重要意义。为了更加贴近实际,在多径条件下并考虑切割效应的情况下对箔条云和载机进行了建模,给出了多径条件下机载箔条质心干扰的仿真模型,模型中考虑了飞机、箔条、导弹三者的实时运动,最后利用此模型从多径效应、导弹初始位置、导弹速度、压制系数等方面分析了其对干扰效果的影响。仿真结果表明,所建立的模型符合实际,可以为军方在作战中制定科学的箔条使用决策方案提供理论指导。

As an important method to protect airplane from attacking from missiles,chaff centroid jamming plays an important role.And a new method was given to simulate the dynamic course based on modeling of chaff cloud and aircraft that in multipath environment and the effect of incising.With this method,the impact of the suppression coefficient,the speed of missile and etc.on the effect off jamming were analyzed.Simulation results show that the model is effective and feasible.
