摘要：

A 532 nm wind lidar system based on a tetrad Fabry-Perot(FP) etalon using steady frequency YAG laser as laser radiation source was designed. In this paper, the fundamental theory of the Doppler wind lidar is introduced, major parameters of emission system, receiver system, emission and receiver optics system and control system were presented. The parameters of the bandwidth and free spectrum range(FSR) width and the width of peak values of outboard double channels based on molecule backscattered signals are designed and analyzed, the parameters of inboard double channels based on aerosols are also designed. The velocity and signal noise ratio of the whole system is simulated. When the value of full width at half maximum is 1.75 GHz, the values of range peaks of the tetrad FPI etalon is 1.1, 1.75, 1.1 GHz, respectively, the system based on outboard double channels may be substituted for boundary atmosphere to lower troposphere wind detection by the system based on inboard double channels. The wind detection of boundary atmosphere to troposphere based on a system may be achieved.
