Simultaneous Estimation of 3D-Position and Velocity of a Moving Random Acoustic Source in Near-Field by Simplified Wavelet Analysis of4Detected Signals

Abstract

This article proposes a simplifid version of previously proposed simultaneous estimation of3D-position and velocity of a moving stationary random acoustic source in near-field by correlation analysis of wavelet patterns of 4 detected signals. By using a simplified wavelet transform at a certain fixed scale value, the method uses 1D-correlation analysis of the wavelet patterns in place of the2D-one in the previous, so that it may save much computation time. The effectiveness of the proposed method is made clear by the results of computer simulations.
