利用扩展惠更斯-菲涅耳原理对高能激光在大气中的传输进行了分析,获得了高能激光准直传输轴上及峰值斯特雷尔比的积分表达式,并使用激光大气传输四维仿真程序对该表达式的适用范围进行了分析及数值模拟验证。结果表明,积分表达式可以很好地适用于无自适应光学系统补偿时的高能激光湍流热晕传输问题,可以用于自适应光学系统补偿时弱热晕条件下的湍流热晕角非等晕问题和弱热晕及中等热晕条件下的湍流热晕聚焦非等晕问题。
The extended Huygens-Fresnel principle is used to analyze the transmission of high-energy laser in the atmosphere, and the integral expression of the high-energy laser collimation transmission axis and the peak-Stray ratio is obtained. The laser atmospheric transmission four-dimensional simulation The program analyzes the application of the expression and validates it by numerical simulation. The results show that the integral expression can be well applied to the problem of high-energy laser turbulent thermal halo transfer without adaptive optics system, which can be used for non-isometric halo of turbulent thermal halo under weak thermal halo when the adaptive optics system is compensated Problems and weak halo and moderate thermal halo turbulence thermal halo non-equidistant problem.
