摘要：

It is presented the calculations of the mean normalized signal power of pulsed coherent Doppler lidar as a function of the intensity of optical turbulence on the propagation path of the probing beam. It is shown that with increasing the optical (refractive) turbulence in the atmosphere, the mean normalized signal power increases with respect to the mean power of the echo of the signal in the absence of turbulence and then decreases and becomes less than the mean normalized signal power in the absence of turbulence. The calculations had performed for the parameters of the Stream Line lidar system. Comparison was made the calculated data with the results of measurements of the mean normalized signal power of the Stream Line after scattering of the probing beam on a screen located at a distance of 500 meters from the lidar.
