Abstract
A hyper-sound detection and ranging system for remote wind measurements that provides all three orthogonal components of a three dimensional wind field on a single transmission pulse utilizing simultaneous beams of acoustic waves. The present invention measures atmospheric wind by transmitting a broad beam acoustic pulse to illuminate a zone of the atmosphere, and then measuring the Doppler shifts in the backscatter signals arrived at the system from various directions along the broad beam projection utilizing simultaneous receiving beams of narrow beamwidth. The simultaneous receiving beams are obtained by means of a hybrid of analog and digital beamforming technologies that enables simultaneous formation of a programmable number of beams in any direction within the designed fields-of-view.
