In order to develop a Rayleigh-Mie Doppler lidar system for detecting mid-to-high wind fields, a set of 532 nm Rayleigh-Mie Doppler lidar verification system based on triple Fabry-Perot interferometer (FPI) was previously built and the actual comparison test was conducted. Using the verification system, the FPI transmission calibration experiment was carried out firstly, and the actual transmission curves of triple FPI were obtained by using the nonlinear fitting method. The spectral width of FPI-1, FPI-2, and FPI-L were 1.20 GHz, 1.22 GHz, and 1.18 GHz respectively, the peak transmission were 0.817, 0.807, and 0.768 respectively, and the peak intervals of FPI-1 & FPI-2 and FPI-1 & FPI-L were 3.91 GHz and 1.25 GHz respectively. Furthermore, the actual wind speed detection sensitivity of the system was given when both of the Mie and Rayleigh scattering signals were incident. Secondly, continuous observation experiment of radial wind speed and comparative observation experiment of horizontal wind field were carried out. The experimental results show that in the single radial wind speed measurement, the system has the capable of detecting wind field at a height of about 10 km and 16 km in the daytime and night respectively with the time resolution of 2 min and spatial resolution of 75 m. In the height range of 2.7 km to 10 km in the daytime and 1.5 km to 10 km in the night, the data of the horizontal wind field measured by the verification system coincide with those measured by the balloon. In the night, 70.8% of the horizontal wind speed and direction data deviation is less than 2 m/s and 10°, and 95% of the data deviation is less than 5 m/s and 15°, which fully verifies the accuracy of the system wind field measurement results.
