The results of calculating the mean intensity and the mean power of laser radiation backscattered by a remote atmospheric layer and detected in the source plane are presented. Behavior of the mean intensity and the mean power of laser echo signal as functions of the refractive turbulence strength, the inner turbulence scale at the different diffraction regimes at the transmitting aperture, and sizes of the receiving aperture are studied.
