讨论了合成孔径雷达(Synthetic aperture radar,SAR)和实孔径雷达(Real aperture radar,RAR)一维扫描方式下的谱域成像实现问题.文中从SAR和RAR扫描下的波数域波散关系入手,分析了这两种扫描方式下的谱域填充区域和成像分辨率,指出了二者的异同,导出了相应的成像算法.单目标和组合目标的雷达成像仿真实验验证了两种扫描方式下成像算法的有效性和理论分析结果.

Radar imaging algorithms of both synthetic aperture radar (SAR) and real aperture radar (RAR) scanning model are studied. It is based on two-dimensional wave equation and basic frequency-wavenumber migration imaging algorithm. This paper analyzes the contrasts between SAR and RAR models on the aspect of spatial spectrum filling form and imaging result resolution. Two simulations are performed to validate the effectiveness and the correctness of radar imaging algorithms and the above theoretical analysis result.
