The purpose of the invention is to improve the accuracy of determining the optical characteristics of the atmosphere. The method is implemented as follows. By the start signal of the control unit 1, a pulse is sent to the studied region of the atmosphere from the source 2. One of the beams of the received radiation undergoes nonlinear transformation. The radiation of each beam by photodetectors 5 and 6 is converted into electrical signals. The signal in the beam after non-linear conversion is measured by the transducer 9, and the beam difference by the transducer 8. In block 10, the values of the received radiation are restored, the sampling period of which is a multiple of the sampling period of the transducer 8. 1 zp f-ly, 1 ill.
