ABSTRACT:
A system and method to detect changes in composite structures using RF signal pattern data interpretation. An RF signal is transmitted from a composite material manufactured structure and a plurality of sensors are employed to measure the RF signal. The measured RF signal is compared to a stored baseline RF signal for the particular structure. Deviations in the measured RF pattern for the structure, or for a structurally-similar composite structure, are automatically analyzed to detect non-visually-detectable defects or other changes in the composite structure. A baseline RF signature is developed for a structure by transmitting a reference RF signal from the composite structure. RF signals are detected by a variety of methods, and the detected signals are compiled and translated into reference and/or test RF signal patterns for the structure.
