Doppler wind light detection and ranging Sampling Rate 1Hz
| Product introduction
The working principle of wind lidar is shown in the following figure. The signal light generated by the fiber laser is emitted into the air to be measured through an optical antenna, and interacts with the aerosol particles to generate a backscattered signal containing their velocity information. According to the Doppler principle, the Doppler frequency shift fd of the echo signal is directly proportional to the velocity of aerosol particles (i.e. wind speed). Therefore, the backscattered signal received by the optical antenna can be processed by combining with the local oscillator light generated by the fiber laser in the system and digital demodulation to obtain the wind field information of the target to be tested.
| Application scenarios
① The specific height of each height layer can be set by the user through the client software
② Can simultaneously output second level data and average data (1 minute, 5 minutes, 10 minutes optional, default to 10 minutes)
③ The second level data volume is about 60MB/day, and the average ten minute data volume is about 100KB/day
④ The statistical data are: signal-to-noise ratio, standard deviation, maximum, minimum, and data reliability
⑤ Power consumption will vary depending on the operating environment
⑥ Class 1M laser safety level is human eye safety level
