抄録

Full polarimetric calibration procedure of a polarimetric Ground Based-SAR system is proposed. As a calibration target, we used a thin wire because the wire can be put more easily than other deterministic target like a dihedral corner reflector. At first, we measured 0 degree, 45 degree and 90 degree inclined thin wire. By using the measured data sets, we derived antenna calibration parameters. After that, we calibrated the system by using the estimated parameters. In order to evaluate this calibration method, we tested the parameters by using 60 degree and 30 degree inclined wire. As a result, we could calibrate 60 degree wire from 1 to 2 GHz but not calibrate 30 degree wire as for amplitude. As for phase term, cross-polarization component could be calibrated for both wires case. But co-polarization component could not be calibrated. The differences between theoretical and calibrated value are within 60 degree up to 3 GHz.
