Zusammenfassung: | The invention discloses a multi-path data synchronous acquisition laser wind measurement system, and relates to the field of laser wind measurement detection. According to the invention, three-channel synchronous 400M data stream processing is realized on a common mainstream process FPGA, operations such as three-path data synchronous acquisition, frequency spectrum and accumulation can be completed, and different specific requirements such as single-direction or three-direction simultaneous measurement, different distance library resolution, improvement of frequency spectrum resolution, improvement of signal-to-noise ratio and reasonable selection of light pulse width can be dynamically realized. Physical characteristics such as wind speed, wind direction, aerosol density and the like of different atmospheric wind layers are obtained, so that wind shear and turbulence intensity of different distance layers in the atmosphere are inverted, the application range is wide, stable operation on low and medium proce |
