Methods for recording and analyzing echo signals with the aim of determining the type of a reflector and sizing it have been developed in ultrasonic flaw detection. The digital antenna focusing (DFA) method makes it possible to reconstruct the image of the entire discontinuity boundary using echo signals reflected from the bottom of the test object taking into account wave type transformation. However, this approach is not always applicable in practice, since the shape of the test object bottom may be unknown. Using the features of the behavior of the reflection coefficient for various types of waves, it is possible to draw a conclusion about the reflector type only from normal beam images. Numerical and model experiments have confirmed the efficiency of the approach proposed. |
