Description

Two aspects of ultrasonic data processing are discussed in this paper: the first one is a brief description of a U.S. imaging software package (detection, location and sizing of defects under coating in the tubes of PWR vessels), while the second concerns the use of discrimination methods for flaw recognition (Adaptative learning network and Fischer's Linear Discrimination Procedure)

Abstract (French)

Cet article presente deux aspects du traitement du signal applique aux donnees ultrasonores. Le premier est une breve presentation d'une application operationnelle (detection, localisation et dimensionnement de defauts sous-revetements dans les tubulures de cuves de reacteurs PWR). Le second concerne l'utilisation de methodes de discrimination pour la reconnaissance de defauts
