Evaluation Of Efficiency Of The Combined Lidar Signal Photodetection Technique

The efficiency of application of the combined photodetection technique for recording the lidar signals of the main mirror of the Siberian Lidar Station (SLS) is evaluated. It is shown that under the lidar signal recording in the photon counting mode, nonlinear distortion of the lidar response is observed in the altitude range from 1 to 26 km. It is shown in that the use of a combined method of the lidar signal recording can significantly expand the range of the detection linearity in the photon counting mode. Experimental testing of the lidar recording system was carried out under the detection of signals of various intensities.
