In the food packaging process, the detection of channel defects in the package's seal is necessary. A new technique is introduced that utilizes the normalized correlation coefficient that is generated by comparison to the echo signal from a normal (reference) sample region. For demonstration purposes, the new technique is compared against the Backscattered Amplitude Integral (BAI) and RF sample (RFS) techniques.
