| 摘 要： | 基于修正的Von Karman湍流谱和Hufnagel-Vally湍流模型上的近似积分理论,结合一种激光光轴瞄准偏差测试系统,利用激光光斑远场实验数据,在一定气象条件下,研究了不同传输距离和波束扩展的变化关系,进而分析了高斯脉冲光束在湍流大气中远场传播时的波束扩展对激光瞄准精度的影响。该研究可为激光光斑瞄准偏差补偿方案的优化设计提供科学依据。

| Abstract: | Based on the analysis of the integrals theory with the modified Von Karman spectrum model and the Hufngel-Valley turbulence profile mode,the article combines a laser spot pointing error compensation system,and adequately using the laser spot far-field experiment data,the relationship between various transmission distances and the beam spreading in certain weather conditions is studied,and then the effect of beam spreading on the laser pointing accuracy were analyzed when the pulsed Gaussian-beam propagation... |
