  • System and method for detecting damage, defect, and reinforcement in fiber reinforced polymer bonded concrete systems using far-field radar
    Patent number: 8244485
    Abstract: A non-contact, far-field radar nondestructive testing (NDT) method is disclosed that is capable of detecting at least one of defects, damages, and reinforcement conditions in near-surface region of multi-layer systems using monostatic inverse synthetic aperture radar (ISAR) measurements and applicable to various types of structural elements. The method includes the steps of conducting far-field monostatic ISAR measurements, executing an imaging algorithm, and executing a progressive image focusing algorithm.
    Type: Grant
