摘要
In view of the widely used 1.55 mu m coherent lidar for wind measurement, the theoretical analysis and numerical simulation is prepared. The theoretical analysis is made of four parts: the principle of wind measurement lidar, laser transmitter, the atmospheric transmission and signal processing. At the same time, the modeling of those parts and a numerical simulation are performed by MATLAB and Simulink. Results of a simple demonstration experiment coincide with those from the models; the coherent heterodyne signal can be clearly detected. Through the reverse calculation of peak of the simulation spectrum, the result accords with the given wind speed.
