- This paper investigates acoustic parameters inversion of wind through developing modified inversion model. By spectrum the analysis of 100 segment measured data at different frequencies, the paper obtains the mean spectrum curve in specific sea state, then uses the mean curve to modify existed models and builds acoustic parameter inversion model. At high frequency, the paper builds comprehensive wind wave noise model by modifying APL and Koopman Ferla model and Knudsen Spectrum shallow water model; at low frequency, shallow water model is established based on Knudsen Spectrum. According to the inversion model in full bandwidth, wind wave signal is inversed by processing the full bandwidth signal in different band by 1/24 octave. The amplitude of the signal follows the Gaussian distribution and the phase follows uniform distribution. The results show that by resorting accurate inversion model, acoustic parameters signal of ocean wind wave can be inversed through data. The results demonstrate the accuracy of the proposed inversion model.
