Acoustic Doppler and Angle of Arrival Wind Detection and Comparisons with Direct Measurements at a 300 m Mast

Abstract

Wind measurements estimated using acoustic sounding systems are compared with direct measurements obtained at a 300 m antenna mast. Different meteorological periods, including very stable to unstable stratification and weak to strong winds, were investigated. It is demonstrated that satisfactory results may be obtained using a simple monostatic Doppler device combined with an appropriate evaluation method. Preliminary tests on an angle of arrival sodar system showed its ability to obtain reasonable wind measurements at least under stable conditions.
