This study explores the use of phased array UT for the potential characterization of hidden regions of impact damage in composites. An idealized ray tracing model was developed, demonstrating the sensitivity of transmitted signals to the hidden impact profile angle and asymmetry in the profile. Experimental studies were also performed highlighting the differences in the response from columnar and trapezoidal profiles. FMC processing algorithms were implemented to improve the signal-to-noise for the pitch-catch characterization routine.
