EMAT Noise Suppression Using Information Fusion in Stationary Wavelet Packets
Original language description
An important issue in ultrasonic nondestructive testing is the~detection of flaw echoes in the presence of background noise created by instrumentation and by clutter noise. Signal averaging, autoregressive analysis, spectrum analysis, matched filtering and the~wavelet transform have all been used to filter noise in~ultrasonic signals. Widely-used wavelet threshold estimation algorithms are not designed for EMAT pulse-echo signals, and therefore do not exploit their unique impulse nature. The~approach toultrasonic signal filtering proposed in this paper is based on stationary wavelet packet denoising with a~threshold influenced by several information sources: a~statistical echo detection, the~amplitude distribution of the~wavelet transform coefficients, and apriori known system frequency characteristics.
