Study of the ultrasonic three-dimensional wind speed measurement methods based on the phase difference
This paper presents a three-dimensional ultrasonic wind speed and direction measurement method based on the space vector analysis.It realizes the wind speed measurement indirectly by using the phase difference to measure the time difference.By using regular tetrahedron sensor configuration,it establishes a mathematical model of the relationship between the phase difference and the wind speed as well as the direction,which solves the problems of traditional methods that always need large structure and high costs.The design presents a viable method for low-cost,small structures and fast three-dimensional wind speed measurement study,which has a broad application prospect in the field of meteorological application and wind energy utilization.
