This study explores the application of algorithms with linear array ultrasonic testing for the characterization of hidden regions of impact damage in composites. An idealized ray tracing model was used to demonstrate the sensitivity of transmitted signals to the hidden impact profile, and a numerical model was used to provide insight on the incident field generated by linear array elements. Experimental studies were performed highlighting the differences in the response from no flaw, columnar and trapezoidal profiles. Algorithms were implemented to process full matrix capture data, register pitch-catch signals with the top delamination location and extent, and improve the signal-to-noise through combining multiple pitchcatch acquisitions. Lastly, a classifier was developed and verification testing demonstrated the ability to distinguish four different hidden profiles, indicating the importance of signal registration for successful classification.
