Abstract:The frequency of laser pulses generate jitter and drift with the changing temperature of the room and the resonant cavity of laser in a differential frequency Doppler lidar wind measurement based on Rayleigh scattering.It brings significantly influence on the measuring accuracy during the wind measurement.In order to eliminate the effects,a dynamic frequency real-time tracking system was designed.The principle,key technique and the chosen core devices were introduced,and the comparison experiment between th...
Keywords:frequency drift  lidar  accuracy of measurement  transmittance
