摘　　要：提出了一种超声波共振式全相位风速风向解算方法,搭建以间距L呈等边三角形分布的3个超声波换能器A、B、C,测量了超声波换能器A、B、C回波初相,根据得到的回波初相解算出从顶点无角度直接吹风和从顶点有角度吹风情况下的风速与风向数据。结果表明,该文建立的全相位风速风向解算方法连续无奇点,与其他方法相比,在输入量相同的情况下风速波动较小,风向解算较准确。In this study,an ultrasonic resonance-based method is proposed for solving full phase wind speed and wind direction.An equilateral triangular distribution of three ultrasonic transducers A,B,and C with an interval L is established.The initial phases of echo waves received by ultrasonic transducers A,B,and C are measured based on the obtained initial phases of echo waves.Furthermore,the wind speed and wind direction data under the conditions of direct wind blowing from the vertex without angle and wind blowing from the vertex with angle are calculated.Additionally,the full-phase wind speed and wind direction algorithm established in this study is continuous and singularity-free.Under the same input conditions,the proposed method exhibits smaller wind speed fluctuation and more accurate wind direction calculation when compared to other methods.
