主　　题：ultrasonic anemometer transducer array blocking effect attack angle inclinometer 

摘      要：Two kinds of measurement errors have been observed in the recently developed UAT-2 ultrasonic *** is the flow distortion produced by ablocking effect,and the other is the angle of attack caused by the vertical misalignment of the ***,we study these errors and discuss the possible correction *** a wind tunnel experiment and numerical simulation,a 3D calibration matrix was developed to correct theblocking effect.In the field test,the angle of attack was detected by an inclinometer settled on the reference plane of the anemometer,and the instrumental misalignment or tilt was corrected by a coordinate *** combined use of an inclinometer and the proposed correction method may help find a new approach for vertical velocity correction.
