| 摘 要： | 极化干涉SAR技术能够提供多种极化状态组合的干涉信息,提高干涉测量的精度。针对含有植被覆盖区域的电磁散射复杂情况,该文通过极化干涉SAR相干矩阵提取不同的极化干涉信息,分析不同极化散射机制对植被高度估计的特定物理意义,用极化干涉SAR仿真数据对不同极化干涉进行高度估计。通过选择最佳的极化干涉提高植被估计的精度,为极化干涉SAR植被成像提供一定的理论依据。

| Abstract: | Polarimetric SAR interferometry (PolInSAR) technique can provide several polarimetric combination states to provide more interferometric information and enhance the precision of interferometric measure. For the complex scattering in vegetation area, the different polarimetric interferometric information is picked up via coherence matrix, and the specifical physics siganification in vegetation area is analyzed. The vegetation height can be obtained by different polarimetric interferometry via PolInSAR simula... |
