RESEARCH ON OPTIMAL SELECTION OF UITRASONIC GUIDED WAVE DETECTION FREQUENCY IN DIRT PIPES BASED ON CHIRP EXCITATION
It is required to conduct repeated multi-frequency test to determine the best detection frequency when taking traditional tone burst as the guided wave excitation of dirt pipe, which had problems of blindness, time and resources consuming. A conversion algorithm from broadband chirp to tone burst wa...
