Ability of High-Energy Laser in Combating Typical Air Targets

为有效评估高能激光对无人机(UAV)蜂群、火箭弹、炮弹及寻热导弹等空中威胁对抗效果,包括完成远距离光电设备干扰致盲、近距离快速毁伤等多层次作战任务能力,基于空间目标常规靶材的激光损伤效应机理,考虑到大气湍流、大气衰减、真空衍射等对光束传输的影响,通过建立1μm连续高能激光系统毁伤能力评估模型,获得了不同大气条件下高能激光对5种靶材的有效毁伤距离。根据计算结果分析可知,在能见度良好的条件下(≥20 km),围绕目标薄弱环节,可完成18 km距离内光电设备致盲以及3 km以内摧毁目标的多层次作战任务,该计算模型可为激光系统设计指标提供理论支撑,可依据不同作战场景、作战距离对激光系统能力提出可靠建议。

In order to effectively evaluate the multilevel combat capability of high energy laser to intercept and destroy air threat targets such as unmanned aerial vehicle(UAV)swarm,rocket,artillery and heat-seeking missile,including remote blinding of electro-optical equipment and rapid damage at a close range,this study is carried out to modeling the damage capability of 1μm continuous high energy laser system.Considering the effect of atmospheric turbulence,atmospheric attenuation and vacuum diffraction on laser transmission in the calculation,five types of irradiated targets are selected to obtain the effectively damaging distance by high energy laser with various atmospheric conditions.The finally simulation results show that it can achieve a multilevel combat assignment of objective blinding within 18 km and destroying the target within 3 km with good visibility condition(≥20 km).The calculation model can provide theoretical basis for the design index of laser system,and provide reliable suggestions for the capability of laser system according to different combat scenarios and combat distances.
