详细分析了基于菲佐(Fizeau)干涉仪测风激光雷达利用条纹重心法反演风速时的方法误差和系统噪声引起的测量误差。提出了方法误差的修正方法,推导出了测量误差理论公式。并用蒙特卡罗方法模拟了低对流层的回波信号,并对其进行条纹重心法风速反演。结果表明：方法误差和气溶胶与分子后向散射比有关,噪声引起的测量误差与信号强度和气溶胶与分子后向散射比有关。在0～5 km,高度采用条纹技术测量的风速误差小于1 m/s。

The method error of gravity method and the measurement error due to system shot noise in wind lidar based on Fizeau interferometer are analyzed in detail. The correction technique of the method error is given, the formula of measurement error is derived. The low troposphere signal simulated by Monte-Carlo technique is used to retrieve the wind velocity. The results show that the method error is related to aerosol-molecule backscattering ratio and the measurement error is related to signal intensity and aerosol-molecule backscattering ratio. At altitude of 0 to 5 km, wind velocity error measured by using fringe technique is below 1m/s.
