摘　　要：强激光武器的出现和投入实战对弹道导弹的生存造成了严峻的威胁。根据激光武器的特性和作战机理,分析了导弹壳体上激光辐照强度的影响因素,得到了导弹壳体上激光辐照强度的计算公式,从而计算出了不同作战距离下的激光辐照强度和光斑半径;建立了机载激光武器(ABL)照射弹道导弹壳体的有限元模型,得到了不同作战距离下弹道导弹被打击后内外壁面的温度分布以及内外壁面温度随时间的变化曲线。以上计算模型及计算结果为激光武器对弹道导弹的毁伤效应分析和激光防护方面的研究提供重要参考。The emergence and the use of powerful laser weapon in the actual combat have caused serious threat to the ballistic missile. According to the characteristics and operation mechanism of laser weapon,the influence factors of laser irradiation power on the missile shell are analyzed and the calculation formula of the laser irradiation power on the missile shell is obtained,so the laser intensity and spot radius under different operational distance can be calculated.Meanwhile,the finite element model that the airborne laser weapon（ ABL） radiates ballistic missile shell is established. The temperature distribution of the interior and exterior wall surface and the temperature change curve of the interior and exterior wall surface of the ballistic missile are obtained accordingly. The above calculation model and the results provide a reference for the damage analysis of the ballistic missile and the research of the laser protection.
