以地基激光辐照飞行靶为研究背景，建立激光迎面辐照和横向辐照靶目标两种交汇场景，考虑激光辐照面域和功率密度分布随靶目标飞行的变化，求解激光辐照参数，建立热传导模型；利用有限容积法，得到飞行靶三维温度场的数值解，分析目标运动性对温度场分布的影响。不同于激光辐照静止目标，辐照参数变化对温度场分布有较大的影响：随着靶目标的飞行，辐照面积逐渐减小，平均功率密度逐渐增加，目标温升速率不断增加；光束与靶目标夹角的变化，引起光束强度空间分布的变化，从而影响温升区域的变化。

Taking ground-based laser irradiating flying target as the background, the encounter scenes were established which included head on irradiating scene and transverse irradiating scene. Considering the varying of irradiating area and power destiny distributing, the laser irradiating parameters were solved, and the heat conduction model was established. The numerical simulation of three-dimensional temperature field of flying target was calculated by the finite volume method. The influence of target moving on temperature field was analyzed. Different from laser irradiating stationary target, the varying of irradiating parameters has a great influence on temperature field distribution. As the target moving, the values of irradiating area decrease gradually, and the values of average power density and the rate of temperature rising increase gradually. The spacial profile of laser beam and temperature rising area are different because of the difference of angle between laser beam and target.
