Özet

We consider non-destructive testing of concrete tunnels for cracks and numerically investigate the feasibility of qualitative microwave imaging for the purpose. More precisely, the linear sampling method is exploited with limited aperture data, which is collected with a linear transceiver array, to sense possible cracks remotely. Preliminary numerical results indicate that the technique can rapidly detect the cracks' location for further investigation.
