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。
Multi-polarization, low frequency ultra-wideband 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 common SAR polarimetric calibration cannot be used. In this paper, with the system echo model, considered the electromagnetic scattering characteristics of the reference calibrator, the polarimetric calibration for the system is proposed. The computer simulation is used to validate the method.
