Abstract
This invention relates to a parametric source Doppler acoustic wind profiler for measuring atmospheric wind conditions. It includes a parametric acoustic source excited by a transmitter generating a pair of primary frequencies and radiates an intermodulation difference frequency. Echoes of the difference frequency are produced by wind induced scatter at the difference frequency which is significantly lower than the transmitted primary frequencies and detected by a single microphone or an array of microphones.
