Detection of Arbitrary Frequency Ultrasonic Guided Wave Signals Based on the Time-Shift Duffing Oscillator
Low detection accuracy and narrow detection range are observed when detecting weak guided wave signals with the Duffing oscillator as a result of a limited frequency band. In order to solve these problems, we proposed a detection method for detecting weak ultrasonic guided waves of arbitrary frequen...
