Abstract
A system and associated method for quickly and automatically determining if the safety and performance of a gun tube have been compromised by firing damage or by an excessive number of fatigue cycles. An electromagnetic resonant cavity inspection provides a means of rapidly evaluating the health of the gun tube by monitoring the resonant frequencies that evolve from microwave signals introduced into the cavity or bore of the gun tube. This approach exploits the high sensitivity of the electromagnetic cavity resonance phenomena. Defects and degradation in the structure's cavity produce quantifiable changes in the quality factor, frequency shifts, and mode splitting.
