High Resolution Deconvolution of Ultrasonic Tracesand localization of flaws, it is frequently desirable to enhance the resolution of the raw B-scan data. In this report we describe the principles and performance of procedures for improving the temporal resolution of the data. The methods are one-dimensional and are applied to successive traces (A-s

Non-Destructive Evaluation in the Time-Frequency Domain by Means of the Wigner-Ville Distributionxed tools which consider time and frequency simultaneously. Among different possible approaches, it is justified that time-frequency distributions related to the Wigner-Ville transform are of special interest. A concrete example, stemming from an underwater acoustics experiment, is provided for supp

Pulse Shaping and Extraction of Information from Ultrasonic Reflections in Composite Materialsher the transmitted waves as appear on the other side of the material, or the reflected waves which return back to the first side. Information about the state of the material is obtained by analyzing the received waves for global acoustic properties as well as local properties that may result from a
