Abstract: There are few methods to restrain noise in the traditional method of measuring wind． In order to better suppress the noise problem，a new method of wind measurement is proposed，which bases on the MVDＲ( Minimum Variance Distortioniess Ｒesponse) beamforming algorithm and combines with a special arc array．Ｒedundant spatial sampling information is obtained by using a four element ultrasonic sensor arc array，and the information received by the array is processed by the MVDＲ beam-forming algorithm to estimate the wind speed and direction information that to be measured． The simulation results show that the estimation of wind speed 0 ～ 60 m /s and wind direction angle 0 ～ 360° can be easily realized． The method is superior to the noise resistance and can be used to measure the wind speed and wind direction angle accurately．
