Abstract
This study introduces an advanced simulation model of radar response on embedded layer in concrete. The applicability of the simulation is verified by comparing the test results with calculated results. In this model, the electromagnetic wave was assumed to have two different propagation modes at the interface (normal incidence and oblique incidence) depending on the subsurface objects. A new approach has also been proposed to analyze the attenuation in each interface which has different electromagnetic properties and the horizontal resolution of target object (reinforcement bar).
Since analytical results by proposed model coincide well with the test results, it is concluded that this simulation technique can be used to analyze radar response on subsurface objects in concrete.
