SOME ERRORS ASSOCIATED WITH ACOUSTICAL WIND MEASUREMENTS THROUGH A LAYER
WHITE SANDS MISSILE RANGE N MEX
An acoustic wind measuring array consisting of a transmitter and two receivers is investigated. The error incurred by assuming that the wind component in the line of sensors is dependent solely on the time delay of the sound front arrival at the two receivers is found. For an orientation suitable for measuring the horizontal flow through a layer, the error is less than 7 for cross-wind components less than 30 mph and the temperature through the layer known to 1 degree centigrade.
