Research on Technology of 1.55μm All-Fiber Coherent Wind Lidar
The monitoring of wind speed is very important in meteorological prediction, safety protection of aircraft and the investigation of wind resources. The 1.55 μm narrow line width all-fiber lidar is used for all optical fiber laser coherent Doppler wind technology research. A set of the motor driven wheel rotation to simulate wind speed measuring device is developed, and the scattering signal is used to produce Doppler frequency shift to calibrate accuracy of the calibration system. The single-pulse energy of the 1.55 μm all-fiber pulse laser is 10 μJ, the pulse repetition frequency is 20 kHz, the pulse width is 200 ns, and the simulated wind speed is consistent with the actual measurement results.
