Abstract
Power fluctuations of a coherent Doppler lidar echo signal caused by turbulent pulsations of the refractive index of air are analyzed. Based on an analytical approach, it is shown that, with an increase in the optical turbulence intensity, the relative root-mean-square deviation of the echo signal power, averaged by microphysical parameters of scattering particles, first increases and then decreases not exceeding the value of 0.5. An experimental dependence of this characteristic on the measurement distance is presented.
