WiFi Satellite Communication Doppler Wind Lidar -40C To 50C Work Temperature
Wind Lidar Working environment temperature -40℃ ~+ 50℃
1,Product introduction
It can be known from the Doppler principle that the Doppler frequency shift fd of the echo signal is proportional to the moving speed of the aerosol particles (that is, the wind speed), so the backscattered signal received by the optical antenna passes through the local oscillator generated by the fiber laser in the system. Optical beat frequency and digital demodulation can be processed to obtain the wind field information of the target to be measured.
