Waveguide invariant estimation based on correlation coefficient of tonal acoustic intensity interference fluctuation
The waveguide invariant is usually not extracted from the striation pattern of broadband continuous spectrum in the low frequency analysis and recording spectrum at low signal-to-noise ratio. In this paper, the correlation coefficient of multi-tonal acoustic intensity interference fluctuation is uti...
