Spatial Resolution of the Pressure Anemometer

Abstract

One of the important characteristics of an anemometer is its spatial resolution. A three-dimensional generalization is given of a method to calculate the transfer function as a function of the wavenumber, devised by Kaimal et al. for a sonic anemometer. The method has been applied to the sensor system of the pressure anemometer, a new type of wind vector measuring instrument. The results, given in a number of figures, show an extremum before the transfer function falls off to its final value.
