which is regarded as the difficulty to ensure the safety and durability of large concrete construction.With practical examples,the paper presents the theory and method that it uses ground-penetrating radar and ultrasonic to detect non-dense areas and holes and shows the detailed process of dealing ...
C-thrue is an all-in-one Ground Penetrating Radar (GPR) for accurate scanning and real time analysis of concrete structures. Construction and service companies as well as civil and structural engineers can now improve the way they locate rebars, voids, post-tension cables, cavities, conduits, a...
Radar systems are provided for mobile platforms that include, in one embodiment, an antenna and a radome. The radome surrounds the antenna, and includes a plurality of transition layers each having a different respective permittivity. The respective permittivities of each of the transition layers ...
