Numerical simulation analysis for detectability of spaceborne lidars

In order to study the effect of the technical parameters of a spaceborne atmosphere sounding lidar on its aerosol detectability,atmosphere backscattering returned signals and signal-to-noise ratio of sounding signal were numerically analyzed by making use of appropriate atmosphere pattern and setting parameters of a spaceborne atmosphere sounding lidar.The detectability of a spaceborne atmosphere sounding lidar about dust and cirruswas simulated.The simulation results revealed that a spaceborne atmosphere sounding lidar's horizontal resolution setting for aerosol detection should be 75km,and its sounding ability for detecting aerosol could achieve the detection requirement at night only and that the horizontal resolution for cirrus and dust detection should be 7.5km.The obtained results offer academic foundation of parameters,setting for manufacture of a spaceborne atmosphere sounding lidar.
