Abstract

A proposed method for measuring ultrasonic wind speed and direction utilizes the quadratic correlation phase method to address limited range issues and low measurement accuracy associated with the phase difference method when the signal-to-noise ratio is low. First, the proposed method uses quadratic correlation method combined with the four-step phase shift method to estimate the phase difference based on wind measuring structure of the opposing-type Array Structures. Then, the two-frequency phase difference method extends the measurement range of ultrasonic wind speed and direction. Finally, we also built an ultrasonic wind measurement system and perform practical tests, showing that the maximum measurement errors for wind speed and direction angles are within

0.28 m / s

and

2.8 °

, which essentially conforms to the ultrasonic anemometer’s design requirements.

基于二次相关双频相位法的超声风矢量测量。

提出了一种利用二次相关相位法测量超声波风速和风向的方法，解决了在信噪比较低时相位差法测量范围有限和测量精度低的问题。首先，该方法采用二次相关法结合四步相移法估算基于对置阵测风结构的相位差；然后，双频相位差法扩展了超声波风速和风向的测量范围。最后，我们搭建了超声波风速测量系统并进行了实际测试，风速和风向角的最大测量误差在0.28m/s和2.8°以内，基本符合超声波风速仪的设计要求。
