The invention discloses a portable wind gauging laser radar Doppler adjusting method which is characterized in that it arranges a Nd:YAG laser; the impulse light sent by the laser incidents into the rim of the illuminating rotation disk through the collimating mirror and the exiting aperture after weakening and delaying; the rotating of the rotation disk makes the brand light at rotation disk rim to generate Doppler frequency shift; the brand light with Doppler frequency shift signal is transmitted by another optic fiber after the receiving drive plate; the other input end of the melting optical fiber coupler generates crossfire signal as reference light which is coupled with the reflecting light with Doppler frequency shift signal by another optical fiber coupler after adjustable attenuator and achieves to wind gauging laser radar receiver to do signal analyzing and processing. |
