摘要
低频UWBSAR系统具有的超宽带特性,大处理角特性和低频特性使得常规SAR辐射校准技术不再适用。针对系统特性,本文给出了低频UWBSAR的辐射校准方法,并在计算机仿真中验证了该方法的有效性。
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.
