Limitations on the use of wide-band transducers in practical non-destructive testing
Abstract
It is shown that short-pulse wideband transducers give good target-range resolution but can also give rise to spurious multipulse echoes in the time domain and to spurious modulation of the echo spectra. If results from targets at different ranges (or pulse shapes at various ranges) are compared, allowances must be made for the changes in pulse shape due to diffraction effects.
