低频

超宽带和大处理角是低频超宽带合成孔径雷达(ultra wide band synthetic aperture radar

UWBSAR)系统的三大特点

针对该系统特点

给出目标散射特性的计算方法

并建立了散射特性与SAR图像的映射关系.最后提出了低频UWBSAR的辐射校准方案

并在计算机上得到了较为理想的仿真结果.

The low frequency ultra wide band synthetic aperture radar (UWBSAR) system has three peculiarities:low frequency

ultra-wideband and large processing angle.Based on these peculiarities

the scattering model of the targets is calculated and mapped to the SAR images.The calibration method is proposed in the end of the paper

and computer simulation is used to validate this method.
