Full Polarimetric Borehole Radar Measurement of a Conducting Cylinder with Dipole and Loop Antenna

We present full polarimetric borehole radar and field experiment results with this radar. This radar consists of four dipole and two loop array antenna elements for each transmitter and receiver. We conducted field experiments to measure a conducting cylinder in soil with the radar. The experimental data showed the co-polarization components are larger than the cross-polarization ones in magnitudes of reflection from a vertical conducting cylinder. It also showed that the cross-polarization components in an inclined conducting cylinder reflection got larger than that in the vertical conducting cylinder. These results agree with the polarimetric property in conducting cylinder scattering. Also, we confirmed the experimental data was in line with the reciprocity theorem.
