| Abstract: | In order to measure wind speed in boundary layer, a direct2detection Dopp ler wind lidar system based on Muli-beam Fizeau interferometer and CCD detector is p roposed. The op tical p roperties of Fizeau interferometer are analyzed. Some parameters degrading interferometer spectrum and resolving power are p resented. The ability of receiving photons number forDopp ler lidar system is studied. Utilizing standard atmosphere parameters and a set of p ractical lidar system parameters, op timization of Fizeau interferometer is imp lemented by numerical simulation. It shows that horizontalwind speed error in boundary layer is less than 1 m / s using the op timized parameters. |
