| Abstract: |
| The C-band synthetic aperture radar (SAR) data from the Bohai Sea of China, the Labrador Sea in the Arctic and the Weddell Sea in the Antarctic are used to analyze and discuss the sea ice full polarimetric information reconstruction ability under compact polarimetric modes. The type of compact polarimetric mode which has the highest reconstructed accuracy is analyzed, along with the performance impact of the reconstructed pseudo quad-pol SAR data on the sea ice detection and sea ice classification. According to the assessment and analysis, it is recommended to adopt the CTLR mode for reconstructing the polarimetric parameters σHH0,σW0,H,and α, while for reconstructing the polarimetric parameters σHV0,ρH-V,λ1 and λ2, it is recommended to use the π/4 mode. Moreover, it is recommended to use the π/4 mode in studying the action effects between the electromagnetic waves and sea ice, but it is recommended to use the CTLR mode for studying the sea ice classification. |

| 本文利用中国渤海,北极拉布拉多海,以及南极威德尔海的C波段合成孔径雷达(SAR)数据,分析探讨了CTLR和π/4等紧缩极化模式对海冰全极化信息重构能力。着重分析哪种紧缩极化模式重构的全极化信息精度最高,以及重构的伪全极化SAR数据对海冰检测以及海冰分类的性能影响。根据本文的分析,对于重构极化参数σHH0,σW0,H,α推荐使用CTLR紧缩极化模式;对于重估极化参数 σHV0,ρH-V,λ1和λ2推荐使用π/4紧缩极化模式。在研究电磁波与海冰作用效果时,推荐使用π/4模式;而在研究海冰分类时,推荐使用CTLR模式。 |
