Optimization of Parameters of a Turbulent Lidar

详细

Experimental and calculated data on the shape of the peak of backscatter enhancement during beam propagation through a turbulent atmosphere are compared. Two schemes of a two-channel turbulent lidar are considered; the ratio of lidar echoes and the factor of turbulence effect on the average scattered light power on the receiver are calculated versus the geometric characteristics of the transceiver. The advisable diameter of the lidar transceiver apertures is 50–70 mm. To create an efficient eye-safe lidar, it is suggested to use a laser operating at a wavelength of 355 nm. The echo and the turbulence effect are estimated for day and twilight values of the background light. A possibility of an UV turbulent lidar to remotely detect turbulent zones in the troposphere is analyzed.
