Effect of Atmospheric Turbulence on Laser Radar

摘要

Effect of atmospheric turbulence on the performance of laserradar is investigated in this paper. The characteristic of the Gaussian laser beam propagating parallel to the ground in weak turbulence is primarily considered. The light intensity fluctuation, beam shifting and spread caused by the turbulence are calculated. The effect of turbulence on laser pulse width is also researched. And then the effect of the atmospheric turbulence on laserradar is concluded.
