Chirp-pulsed eddy current testing for crack detection in low-carbon steel
International Journal of Reconfigurable and Embedded Systems (IJRES)This paper introduces a signal processing feature for chirp-pulsed eddy current testing (C-PECT) to improve crack detection in low-carbon steel, a common material in maritime structures. While C-PECT is an established technique, inspecting ferromagnetic materials is challenging due to significant background noise from lift-off variations and material ...
