Computer model study of pseudorandom noise modulation continuous-wave (PRN-cw) backscatter lidar

摘要

Abstract: We present a computer model for simulation of PRN-cw atmospheric backscatter lidar performances. The program for calculation operates on a PC type computer. The model covers a variety of cases for the lidar platforms: satellite borne (nadir-looking), airborne (both nadir- and zenith-looking) and ground based. The estimation of the lidar response function includes the following inputs: A) ESA/ATLID cloud and aerosol backscatter/extinction model and molecular atmosphere backscatter and extinction model, based on US standard atmosphere. B) Terrain surface function model. C) Different M-sequences modulation formats, sub-system parameters and solar background. !14
