Abstract
One primary concern for marine propeller design is the incipient tip vortex cavitation. The present study elaborates its hyperbolic localization, which is subjected to an estimation of time difference of arrival between measured acoustic signals. The generalized cross-correlation with phase transform, a conventional algorithm for time delay estimation, tends to be susceptible to the noise outside the frequency band of signal. In order to suppress these effects, we propose a weighting function, resembling the rectangular window in frequency domain. By further noting that the signal arisen by the tip vortex cavitation can be fall into the cyclostationary type, the spectral kurtosis is employed to design the optimum band of the frequency weights. Finally, the method is verified by experimental measurements in the water tunnel.
