Lasse Karlsen: Method and a device for determining wind velocity or velocity of a fluid and use thereof. Limbach & Limbach L, November 9, 1999: US05979234 (17 worldwide citation)

A method and apparatus for determining the velocity of wind (or another fluid) in which one or more receiving acoustic detectors at (e.g. a location (A(r,t))) on the ground are arranged to measure the phase direction of arriving waves from one or more sound sources (at locations S(r,t)), all of whic ...

Karlsen Lasse: A method and a device for determining wind velocity or velocity of a fluid and use thereof. Karlsen Lasse, September 3, 1997: EP0792461-A1 (1 worldwide citation)

One or more receiving acoustic detectors at e.g. a location (A(r,t)) on the ground are arranged to measure the phase direction of the arriving waves from one or more sound sources (at locations S(r,t)), all of which may be fixed or moving. A mean value of the wind and its gradient can be obtained al ...
