摘要

针对二维超声波风速风向传感器输出的风向信号普遍存在风向角瞬变的问题

研究了产生风向角瞬变现象的原因

并提出了一种基于幅值—符号分解的风向修正算法。理论分析和实验结果表明:风向信号中的风向角瞬变是由传感器的量程限制造成的;基于幅值—符号分解的风向修正算法能在不改变风向角所表征的方位特征的前提下消除风向角瞬变。

Abstract

Aiming at problem that wind angle transient is common in wind signal for 2D ultrasonic anemometer

causes of this problem is studied

and a correction algorithm based on magnitude / sign decomposition is proposed.Theoretical analysis and experimental results show that the wind angle transient is arised by range limits of sensor

and the correction algorithm based on magnitude / sign decomposition can eliminate this problem without changing orientative feature represented by wind angle.
