大气湍流对激光照射精度影响分析和计算

Analysis and calculation of influence of atmospheric turbulence onlaser irradiation accuracy

摘要: 为了评估大气湍流效应对激光照射器照射精度的影响，理论分析和数值计算了由于大气湍流引入的激光照射误差随着照射距离、大气湍流强度、激光光束半径的变化关系。结果表明：随着照射距离和湍流强度的增加，以及激光光束半径的减小，大气湍流引起的激光照射误差增大，大气湍流对现有机载光电稳瞄系统照射精度影响为10 rad~30 rad。

Abstract: In order to investigate the effects of atmospheric turbulence on the designation accuracy of the laser designator, the designation accuracy was deduced and evaluated, which was changed with designation range, atmospheric turbulence and beam radius. The results show that the designation error would be increased significantly as designation range and atmospheric turbulence increase, as well as the receiver aperture decreases. The designation error induced by atmospheric turbulence is about 10 rad~30 rad.
