【摘要】Wind speed is an important factor meteorological forecast,accurate forecasting of wind speed,has certain influence on people’s production and living. Two-dimensional ultrasonic wind speed sensor is one of the most important way of wind speed measurement in meteorology and industry,on the basis of traditional ultrasonic
