  • Multi-polarization, low frequency Ultra Wide Band Synthetic Aperture Radar (UWB SAR) is one of the most important aspects of the radar technology. The low frequency, UWB and large processing angle result that the polarimetric calibration for regular SAR system cannot be used. In this paper, based on the frequency-domain processing model of the multi-polarization, low frequency UWB SAR system, with the consideration of the low frequency UWB electromagnetic scattering characteristics of the calibrators, the polarimetric calibration method is proposed. The computer simulation is used to validate the method.
