摘要 多极化,低频超宽带(UltraWideBand,UWB)合成孔径雷达(SyntheticApertureRadar,SAR)是雷达技术未来发展的一个重要方向。系统的低频特性,UWB特性和大处理角特性使得常规SAR极化校准不再适用。该文基于多极化低频UWBSAR频域处理模型,考虑了极化校准中定标体的低频超宽带电磁散射特性的问题,给出了极化校准方法。计算机仿真验证了该方法的有效性。 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.
