| 摘 要： | 在海洋的合成孔径雷达图像中,降雨（雨团）通常能引起依赖于雷达频率和极化的形状不规则的亮暗斑状图案,影响着合成孔径雷达图像的正确解译。基于C.Melsheimer的双极化仿真方法,首次对海洋雨团C、X波段全极化合成孔径雷达归一化雷达后向散射截面积进行仿真。仿真结果补充了双极化仿真的不足,更加全面地揭示了海洋雨团合成孔径雷达回波在不同波段不同极化下的特点,有助于合成孔径雷达图像的正确解译和降雨定量化研究。 |

| Abstract: | Rain showers (rain cells) often cause distinct signatures on synthetic aperture radar (SAR) images of the ocean, which consist of irregularly-shaped bright and dark patches, strongly depend on radar frequency and polarization, and directly affect the interpretation of SAR images. Based on the dual-polarized simulations proposed by C. Melsheimer, the effective normalized radar cross section (ENRCS) of SAR echo of rain cells on C and X band with full-polarization is simulated for the first time. The simulatio... |
