摘　　要：综述SHiELD项目和美国空军机载激光武器发展路线。在典型参数设定下仿真计算机载激光武器对战术导弹目标的毁伤距离,并给出相关的变化关系曲线,供系统设计和评估参考。基于衍射极限限制和聚焦发射两种方法得到的结果呈现很好的符合性,表明激光光束在聚焦发射时同样遵从衍射极限限制特性。仿真结果还表明,除了增加激光发射功率、延长目标照射时间外,改善光束质量和加大发射口径对增大照射在目标上的激光功率密度、提高目标毁伤距离尤为有效。最后,围绕战斗机平台的尺寸/重量/耗能约束、高速飞行环境和自卫作战要求,探讨若干挑战性技术问题。The SHiELD program and the AFRL broad timeline of airborne laser weapons development were reviewed. The damage distance of airborne laser weapon against tactical missile targets were computed with assumed typical parameters,giving related curves of variation as references for system design and evaluation. The results based on the diffraction-limited and the focusing emission method appeared to be in good agreement,implying that the laser beam in focusing emission complied similarly with the diffraction-limited characteristics. It was also showed that except for raising laser power and prolonging on-target illuminating time,improving beam quality or using larger emission aperture was particularly effective in increasing the laser power or energy density onto the target and thus the damage distance. Finally,several challenging technical issues were discussed,concerning the jetfighter platform’s SWaP constraints,high speed flight condition and self protection mission requirements.
