Aiming at the problems of poor environmental noise suppression effect and low accuracy of wind speed and directionmeasurement in the existing ultrasonie wind measurement system in practieal application, an array ultrasonie sensor based on high-ordercumulant is proposed to measure wind speed and direction. The proposed method adopls the structure of an ultrasonie wind measurementsystem, which consists of an ultrasonie transmitting aray and five ulirasonic receiving array elements. On the structure of the system,muli-signal clasification(MUSIC)algorithm based on the high-orler cumulant is adopted to realize the effective measurement of windspeed and direction under Gaussian white noise or Gaussian mixed noise, which can effectively suppress the interference of whiteGausian noise and color noise. Compared with wind measurement method using correlation algorithm, the proposed method has highernoise suppression ability and higher measurement accuraey of wind speed and direction. Finally, the effectiveness of the proposed methodis verified and analyzed through simulation experiments and measured data verification experiments. Experimental results show that themeasurement errors of wind speed and wind dircetion Angle are 2.3% and-2°,respectively, which basically meet the technicalrequirements of ultrasonic wind measurement methods.
