The purpose of this research was a three-dimensional imaging of terrain using polarimetric and interferometric synthetic aperture radar data. This polarimetric interferometric data-take requires very precise measurement for airborne radar within several cm repeat pass flight. Since this condition was too difficult to achieve for actual airplane, we paid main attention to classification and decomposition of polarimetric SAR data. The final purpose of radar remote sensing would be to find the details of target based on the polarimetric information. Thus, the research results conducted during the period are :1.Establishment of the principle of radar polarimetryIt is important to establish a unified theory for polarimetric radar sensing. The principle of radar polarimetry from basic to its applications has been described in the research report.2.Establishment of X-band polarimetric SAR system(1)Set-up of polarimetric interferometric SAR in anechoic chamber.(2)Validation of acquired data from polarimetric point of view.3.Development of target classification(1)Search for best descriptor of polarimetric information among the statistics of the second order of cross-correlations, eigenvalue, polarization basis transformation, etc.(2)Development of four-component scattering model for polarimetric SAR image decomposition.(3)Ground truth for the four-component decomposition using Pi-SAR data acquired with Pi-SAR over Niigata area.

本研究的目的是利用偏振和干涉合成孔径雷达数据对地形进行三维成像。这种偏振干涉测量数据需要非常精确的测量，机载雷达在几厘米内重复通过飞行。由于这一条件在实际飞机上很难实现，因此我们主要关注极化SAR数据的分类和分解。雷达遥感的最终目的是根据极化信息找到目标的细节。因此，在此期间进行的研究结果是：1。雷达极化原理的建立建立统一的极化雷达传感理论具有重要意义。本研究报告叙述了雷达偏振测量的基本原理及其应用。x波段偏振干涉SAR系统的建立(1)暗室偏振干涉SAR的建立。(2)从极化角度对采集数据进行验证。目标分类研究进展(1)在二阶互相关、特征值、极化基变换等统计信息中寻找极化信息的最佳描述符(2)极化SAR图像分解的四分量散射模型的建立。(3)利用新潟地区Pi-SAR获取的Pi-SAR数据进行四分量分解的地真值。
