The measurement of atmospheric wind field is of great significance for global climate change, sea storm detection, accuracy of daily weather forecast, and even national military security. Space-based coherent wind light detection and ranging (LiDAR) has attracted wide attention due to its high time-space resolution, high sensitivity, real-time detection, and small volume. Most spacecraft have micro-vibration disturbance sources, which can influence the signal-to-noise ratio (SNR) of coherent wind LiDAR. Based on the principle analysis of coherent wind LiDAR system, this paper analyzes the influence of satellite micro-vibration on the signal-to-noise ratio of the coherent wind LiDAR, based on the measured data of a certain type of micro-vibration. The experimental results show that satellite micro-vibration has a certain effect on the signal-to-noise ratio of coherent wind LiDAR. When the mismatch angle is 3.77 μrad, the signal-to-noise ratio fluctuates between -1.5 dB and 1.36 dB, and the impact is relatively weak. From a micro-vibration perspective, a satellite platform can meet the detection requirements of a coherent wind LiDAR.
