On the basis of Mie scattering theory and Taylor′s frozen hypothesis,a dual laser non-Doppler lidar wind measurement system is developed in order to design a low-cost,high-precision,telemetered wind speed measurement device.A 532 nm laser is used as the light-emitting unit,a charge-coupled device (CCD) as the light-receiving unit,and a computer as the information processing unit in the design of the experimental non-Doppler lidar wind measurement device.Under conditions of 3 m/s and 2 m/s wind speed,the foward scattered echo signals of the dual laser beams produce the light intensity maps of the left and right lasers,respectively.After analyzing the light intensity map,it is possible to calculate how long it would take for an aerosol to migrate from one laser beam to another.Using the distance between the two laser beams,the wind speed measurements are obtained under the conditions of wind speeds of 3 m/s and 2 m/s.The errors are 7% and 7.33%,respectively,between the mean measured value and the actual value.The non-Doppler lidar wind measurement device is simple in design,affordable,and has a significant practical application.
