| Abstract: | Regular radiometric calibration technique cannot be used for low frequency UWB SAR system for its UWB, large processing angle and low frequency characteristics. Considered these characteristics, the radiometric calibration for low frequency UWB SAR is given, and the computer simulation is used to verify this calibration method. |

| Keywords: | Low frequency UWB SAR Radiometric calibration Resonance scattering |
