Abstract. The paper solved the problem of determining the amount of received scattered optical power of third-party weakly diverging laser beams propagating in the Earth’s atmosphere by a passive laser locator (lidar) in a  transparent atmosphere, and the radius of the lidar action was determined. At night, without sunlight, the lidar range can be more than 10,000 km when detecting beams with a power of about 100 kW in the 1 Hz frequency band. The lidar photodetector is made on the basis of an avalanche photodiode with a detecting ability (NEP) equal to 3.2 .10-14. In the presence of solar illumination, the range is reduced by an order of magnitude due to the additional noise of the illumination falling on the avalanche photodiode. However, if  a  wavelength of laser radiation is wellnoun, it is possible to use a narrow-band interference filter in front of the photodetector. In this case, the influence of solar illumination can be almost completely eliminated and the range of the lidar increases. Rayleigh scattering detection in the weakly turbid atmosphere of the Earth can also be used for long-distance communication or synchronization of remote sites over long distances. Experimental and theoretical data are consistent with each other, which confirms the correctness of the theoretical approach to the problem being solved.

Keywords: lidar, Rayleigh scattering, atmosphere, sunlight.
