Abstract This paper researches the bistatic Doppler wind lidar, which can detect wind field precisely. Firstly, to meet the need of precisely detecting, non-line-of-sight single-scatter propagation model is creatively adopted for volume scattering, which is usually used in the optical communication. Secondly, Frequency discriminator of bistatic Doppler wind lidar is simulated, including the echo signal and retrieval algorithm of wind field. In order to analyze the scattering and extinction coefficients precisely, the relative humidity of sounding data is utilized. Thirdly, the data set of radiosondes is put forward, which lays a good foundation for simulating and verifying the atmospheric wind speed. Using the data set, Doppler speed and wind speed’s profile are simulated. The result shows that the error of wind speed is less than 1 m/s, bistatic wind lidar is available to detect the wind field precisely.
