机载高能激光辐照典型目标毁伤特性研究

Research on the Damage Characteristics of Airborne Laser Irradiation on Typical Aerial Targets

摘要:

现有的激光武器相关研究多集中于陆海基平台，主要模拟分析激光的传输特性和毁伤效果，但对战场大气环境、激光工作海拔高度等因素对激光到靶功率密度的影响研究不足，尤其缺乏机载激光武器辐照目标光束传输的深入探讨。针对该问题，考虑了大气湍流、衰减、衍射、散射及载机抖动等多重因素对光束传输的影响，建立了高空作战环境下机载高能激光武器的大气传输模型，计算了机载激光辐照目标的到靶光斑尺寸和功率密度，探讨不同效应参数与激光到靶光斑尺寸和功率密度的关系。该研究不仅为机载激光武器的参数指标优化提供了理论支撑，也为后续空中对抗场景的作战研究奠定基础。

Abstract:

Current research on laser weapon systems predominantly focuses on land- and sea-based platforms, primarily investigating laser transmission characteristics and damage effects. However, there remains insufficient exploration of critical factors influencing laser irradiance at the target, particularly regarding battlefield atmospheric conditions and operational altitude variations, with notably limited in-depth analysis of airborne laser beam propagation through aerial combat environments. To address these research gaps, this study establishes an atmospheric transmission model for high-altitude airborne laser weapons that systematically incorporates multiple influencing factors including atmospheric turbulence, attenuation, diffraction, scattering effects, and aircraft platform jitter. Through comprehensive numerical simulations, we calculate the target spot size and power density distribution of airborne laser irradiation, while quantitatively analyzing the correlation between various operational parameters and resultant beam characteristics. This investigation not only provides theoretical foundations for optimizing performance parameters of airborne laser weapon systems, but also establishes critical groundwork for subsequent operational analyses in aerial engagement scenarios.
