dc.description.abstract <p>Eddy current technique is a widely used nondestructive testing (NDT) method in aircraft wheel inspection. Commercial wheel inspection systems used by airlines perform a helical scan of the wheel outer surface and produce a strip chart record of the inspection signal. In practice, the eddy current signals are often contaminated by noise, which makes the interpretation of the strip chart record very difficult In commercial systems, the problem of data interpretation is rendered difficult due to the fact that the hardware configuration (narrow band pre-filter and low sampling rate) eliminates the information about the shape and spectral differences between the defect signal and noise. In order to improve the performance of the wheel inspection system, a PC based signal analysis system was developed to obtain a more accurate interpretation of the eddy current inspection signal.</p>
