Abstract

A lidar response simulator has been created that makes it possible to generate an optical signal close in shape and intensity to a real lidar signal in the temperature measurement channels at the main lidar of the Siberian Lidar Station. An experimental evaluation of the linearity range of the photodetection system has been carried out. The paper shows a block diagram of a stand for experimental evaluation of the linearity range of a lidar photodetection system with the ability to synthesize a pulsed optical signal. It is shown that when a signal is recorded in the photon counting mode, nonlinear distortions are observed at an average counting pulse arrival frequency of 2.5 MHz.
