Analysis of saturation signal correc

Analysis of saturation signal correction of the troposphere lidar

Usually, lidar detection systems are optimized for the measurement of the low intensity signal using the photon counting technique, but this approach results in the nonlinear signal response for the higher intensity signal.The problem is successfully solved by the combination of analog-to-digital (AD) and photon-counting (PC) detection.The optimized processing procedure of the signal combination of AD and PC is described, and the corrected result is analyzed and compared with the results by the dead-time correction method.In this way, the accuracy of wind and aerosol measurement in the nonlinear range is improved.In addition, the signal-to-noise ratios (SNRs) of the two detection methods of AD and PC are compared in the overall dynamic range of signal for the performance analysis.
