Abstract
Deconvolution can be a valuable technique for interpreting results of ultrasonic nondestructive evaluation (NDE) tests of materials. This is especially true for state of the art hybrid materials. In this paper, a new H ∞ deconvolution filter is presented. The filter is applied to typical ultrasonic NDE data, including through-transmission data for aluminum and composite samples. The results are compared to those obtained from a Wiener deconvolution filter. The performance of the H ∞ filter is as good or better than the performance of the Wiener filter.
