摘要
强激光的大气传输效应是影响激光武器系统性能的重要因素。通过理论分析和数值计算表明,光功率衰减主要跟能见度有关,而光束辐照面积的增加主要是由湍流和热晕的强度决定的。激光武器系统仅适用于中低强度湍流和热晕,除此之外,在其它条件下,激光武器系统的作用距离将大大受限。
The atmospheric effect of high energy laser is the key factor to the system performance of laser weapons.Through theoretical analysis and numerical simulations,it has been proved that the power attenuation is mainly related to the visibility of atmosphere,and the increase of beam spreading is up to the intensity of turbulence and thermal blooming.The laser weapon system is only applicable to medium and low intensity turbulence and thermal blooming,under other conditions the efficient distance of such laser weapon system would be greatly limited.
