Analysis and calculation of influence of atmospheric turbulence onlaser irradiation accuracy

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.
