Abstract
A system for remote measurement of wind velocity and direction. An acoustic echo transmitter for directing a beam of acoustic energy toward a zone, and a plurality of receivers for receiving acoustic energy scattered by wind in the zone, with each receiver output having a doppler frequency component. A system which permits positioning the receivers at various elevations and various distances and angles from the transmitter, and a system particularly sensitive to measurement of vertical wind velocity.
