For curved blocks, where the inside diameter can significantly alter the reflected pressure distributions, this is probably an effective requirement to ensure similar condition between calibration and component scanning. However, when flat parallel surfaces are concerned the concerns for matching thickness of calibration block to component thickness seem to be misplaced. This report details the modelling of echo responses from the traditional "side-drilled-hole" calibration target. Distance Amplitude Correction curves (DAC curves) are simulated by observing the echo-dynamic responses for direct and skip paths on blocks of different thicknesses.
