TRANSIENT WAVE ESTIMATION - A MULTICHANNEL DECONVOLUTION APPLICATION

The evolution of new concepts in wave theory have led to proof-in-principle experiments aimed at validating the generation of a specified wave front. Not only have these concepts initiated research in transient wave theory, but they have also caused renewed effort in multichannel signal processing. In this paper, the development of a processor to deconvolve a transient acoustic wave from sensor array measurements is discussed. The design of the multichannel deconvolver coupled with model-based signal processing techniques using acoustic pressure field measurements is discussed. Here, it is shown that an efficient solution to this problem can be obtained using a vector form of the Levinson-Wiggins-Robinson (LWR) algorithm. © 1990, Acoustical Society of America.
