Backscatter lidar signal simulation applied to spacecraft lidar instrument design
Abstract
In the framework of the existing scientific cooperation, between CEILAP laboratory and IPSL Institute Pierre Simon Laplace from France, devoted to the deployment of Lidar instrument with applications in many field of research in the Atmosphere a new branch of scientific research is now starting involving Lidar in Space Technology. This new research branch is now considering at CEILAP with a joint effort with CONAE at Argentine for the next future spatial mission. In this context the deployment of Lidar in space is necessary to improve our knows of the meteorological dynamic and radiative process in the South American region in the whole troposphere and in the lower stratosphere. With the objective to well asses this future mission a simple model for prediction of backscatter lidar signal from spacecraft platform has been used to determine dimensions and detection characteristics of lidar instrument. Backscatter signal was obtained from an ideal atmosphere with a molecular density as a function of height and in different conditions for aerosols density charge in the lower and higher troposphere. Indeed, the effects of minor atmospheric components are also include in the calculations of backscatter lidar signal at laser operating wavelength. Signal to noise consideration in the interval of the possible dimension of the instrument parameters permit us to constraint telescope receiving area and to derive maximum range achievable, integration time and final spatial and temporal resolution of backscatter profiles.
