Inherent wave estimation on ultrasonic non-destructive testing using fuzzy inference

Abstract

This paper proposes the new method for suppressing the inherent wave of the sensor system. The inherent wave often prevents from analyzing the signal of target. Previous method calculated the inherent wave to solve this problem using two assumptions. However, the calculated wave is differ from the original inherent wave in unsatisfying the assumptions. Therefore, the new method estimates the wave using fuzzy-logic without the assumptions. As a result, this method was able to detect with higher accuracy than previous method. © Springer-Verlag 2001.
