Description

Noise-corrupted flaw signals with known contributions due to flaw scattering are needed to study flaw detection and characterization approaches. The inability to create these “known flaw” signals which are corrupted with acoustic noise (e.g., grain scattering noise) has presented a problem to the nondestructive evaluation (NDE) community for years. An approach is needed for creating noise-corrupted flaw signals which can be used as a basis for studying the impact of different flaw types, measurement system configurations, signal-to-noise ratios (SNRs), acoustic noise types, etc. on digital signal processing algorithms which are being developed.
