本文介绍了利用极化合成孔径雷达层析成像(POLTOMSAR)来表征散射体的第一步。它是层析成像数据处理的逻辑扩展，包括利用电磁波的矢量特性。介绍了对被测目标偏振态的估计。它基于适用于MUSIC算法的修改后的信号模型。这使得有可能确定被检测对象的物理性质，这是使用经典方法不可能的，除非具有正在研究的场景的基本事实。实验结果显示了德国航天研究中心在德国奥伯法芬霍芬附近的一个试验场上获取的L波段的多基线数据集。
This paper presents the first step to characterise scatterers using polarimetric SAR tomography (POLTOMSAR). It is a logical extension of the tomographic data processing, which consists to use the vectorial properties of electromagnetic waves. An introduction to the estimation of the polarisation state of retrieved target is proposed. It is based on a modified signal model adapted to the MUSIC algorithm. This makes it possible to determinate the physical nature of detected object, which is not possible using classical approach, unless having the ground-truth of the scene under study. The experimental results are shown using a multibaseline data set acquired in L-band by DLR’s experimental SAR (E-SAR) on a test site near Oberpfaffenhofen / Germany.
