通过对海南省南保港附近海面ＳＩＲ－Ｃ／Ｘ－ＳＡＲ全极化数据的定量研究，对比研究了该海面不同风区海面的全极化信息特征，定量分析了海面散射的极化信息和极化状态的空间结构情况；用散射矩阵的速解释了不同海区的散射强度对应关系；对比海面散射极化响应可以确定不同成长类型的粗糙海面类型；用极化响应图的对称特点界定“长尺度”和“短尺度”海面；建立全极化海面散射模型。讨论了海面电磁散射的贡献与雷达系统参数之间的定量关系可以通过极化响应建立模型，同散射信号的强度信息一样，散射场的极化信息是海洋雷达定量遥感不容忽视的重要信息源。 Through the quantitative study of the SIR-C / X-SAR data of the total ocean near the Nanbaogang Harbor in Hainan Province, the characteristics of the total polarization of the sea surface in different windward regions of the sea are comparatively studied. The polarization information of the sea surface is quantitatively analyzed. The spatial structure of the polarization state; the scatter matrix velocity explains the corresponding relationship between the scattering intensity of different sea areas; the contrast of the scattering response of the sea surface can determine the different growth types of rough sea surface types; Scale “and” short-scale "sea surface; establish the fully polarized sea surface scattering model. It is discussed that the quantitative relationship between the contribution of sea surface electromagnetic scattering and the radar system parameters can be modeled by the polarization response. Like the intensity information of the scattered signal, the polarization information of the scattering field is an important source of information that can not be ignored in the quantitative remote sensing of marine radar.
