| 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。基于系统回波模型,同时考虑定标体的电磁散射特性,给出了适合该系统的极化校准方法。计算机仿真验证了该方法的有效性。

| Abstract: | Multi-polarization, low frequency ultra-wideband synthetic aperture radar (UWB SAR) is one of the most important aspects of the r adar technology. The low frequency, UWB and large processing angle result that t he common SAR polarimetric calibration cannot be used. In this paper, with the s ystem echo model, considered the electromagnetic scattering characteristics of t he reference calibrator, the polarimetric calibration for the system is proposed . The computer simulation is used to validate the method. |
