Acoustic radar offers a reliable new technique for remotely measuring vector wind velocity. Engineered antenna systems have been constructed that effectively reject noise interference, and corresponding detection logic has been developed that identifies the wind velocity from the processed signal. Recent tests have demonstrated the agreement between the wind velocity measured by acoustic radar and that measured by conventional anemometer and vane instrumentation. Data from these tests are compared, representative differences between the two wind measurement techniques are shown, and statistics of the observable wind velocity are calculated. In addition, different system configurations and processing techniques are described that respond to various user requirements.
