A distant real-time radar NDE technique for the in-depth inspection of glass fiber reinforced polymer-retrofitted concrete columns
نویسنده
چکیده
A novel real-time radar NDE technique for the in-depth inspection of glass fiber reinforced polymer (GFRP)retrofitted concrete columns is proposed. In this technique, continuous wave radar signals are transmitted in the far-field region (distant inspection), and reflected signals are collected by the same signal transmitter. Collected radar signals are processed by tomographic reconstruction methods for real-time image reconstruction. Indepth condition in the near-surface region of GFRP-concrete systems is revealed and evaluated by reconstructed images.
