摘　　要：大气对战术激光造成的光束偏转将使战术激光脱离目标,通过对光束偏转的理论分析和仿真研究,结果表明折射率结构常数和离地面高度是影响光束偏转的重要因素。对光束偏转提出了简单的预补偿方法,从而可以确保战术激光精确到达靶面。The beam bending through atmospheric propagation would make its deviation from the target. Through theoretical analysis and numerical simulations, it has been proved that the refractive index structure constant and altitude are the most important factors to affect beam bending. A simple pre-compensation method is introduced, which could ensure the tactical laser arrive target accurately.

关 键 词：光束偏转 折射率结构常数 自适应方法
