Summary:Radomes are used to protect critical communications and radar hardware from exposure to adverse environmental conditions while providing the necessary aerodynamic characteristics for airborne systems. Near-field microwave and millimeter wave nondestructive evaluation methods are well-suited for inspecting these structures since signals at these frequencies readily penetrate through these structures and reflect from different interior boundaries revealing the presence of a wide range of defects such as disbond, delamination, moisture and oil intrusion, impact damage, etc. This paper presents the results of a comprehensive experimental effort using near-field imaging techniques (producing images with high spatial resolutions) at several frequency bands in the microwave and millimeter wave regions as well as electromagnetic simulations for detecting and evaluating the presence of disbonds in such structures.
