AI Technical Summary
In existing atmospheric environmental monitoring, the mixed observation mode of multiple devices affects the consistency and accuracy of monitoring data, making it difficult to meet the requirements for high precision.
A coherent Doppler lidar system is adopted, which splits the continuous laser into one main laser and four auxiliary lasers through a beam splitter. The return light is received by the main axis and the off axis transceiver modules respectively. The polarization electrical signal is obtained by the dual polarization coherent detection module. The signal acquisition and processing module determines the wind field and polarization rate information.
It has improved the consistency and accuracy of monitoring data, met the requirements of high-precision atmospheric environment monitoring, reduced system error coupling, and improved the ability to acquire wind field and polarization rate information.
