A coherent laser radar or lidar device (2; 20; 84; 90) for measuring wind speed is described that comprises a transmitter for transmitting a beam of light to a remote probe volume (6; 54) a receiver for detecting back-, scattered light and an analyser for calculating wind velocity at the remote probe volume from the Doppler shift in frequency of the detected backscattered light. The analyser is arranged to monitor for the presence of and/or to ensure the calculated wind speed is corrected for any Doppler , frequency components of the detected back-scattered light that arise from backscatter off cloud located at a range greater than the range of the remote probe volume. It is described …
