摘要
Methods and systems for detecting features in thin-wall structures are provided. A plurality of ultrasonic waves are generated within a thin-wall structure. At least one echo from the plurality of ultrasonic waves within the thin-wall structure is detected. The at least one echo is processed to determine a position of at least one feature in the thin-wall structure based on Embedded Ultrasonic Structure Radar (EUSR) beamforming performed in the frequency domain.
