Abstract
Abstract A system for remote and continuous measurement of wind velocity and direction. A system being an acoustic echo system or acoustic radar transmitter for directing acoustic energy to a zone, and one or more receivers for receiving acoustic energy scattered by wind in the zone, with each receiver output having a doppler frequency component varying as a function of wind velocity in the zone, with a signal processor having the receiver outputs as inputs for providing a processor output representing wind velocity.
