Abstract:

The possibility to measure wind velocity and direction with a 2-mm pulsed coherent Doppler lidar under conditions of weak echo signal is investigated. It is shown that the use of the filtered sine wave fitting of the radial wind velocities, measured by the lidar, allows us to obtain estimates of the wind velocity vector components with acceptable accuracy under low signal-to-noise ratio up to values of -20 dB.

Keywords:

coherent Doppler lidar, signal-to-noise ratio, wind
