| 摘 要： | 极化合成孔径雷达干涉测量(PolInSAR)是目前雷达遥感的前沿领域之一,它综合了极化和雷达干涉技术(InSAR)的特点.文中应用极化干涉相干最优化技术处理了Amazon雨林地区的真实L波段PALSAR全极化数据,得到该地区的数字高程模型(DEM).与常规的单极化InSAR技术进行对比,证明了利用极化干涉技术可以显著提...

| Abstract: | PolInSAR,as a new frontier developed recently in radar remote sensing,has the advantage of PolSAR and InSAR.In the paper we retrieve the elevation height of terrain making use of interferometric,fully polarimetric radar remote sensing L-band data of the Amazon rain forest.Compared with conventional single-polarization,PolInSAR can dramatically improve the interferometric coherences,especially in the vegetation area.Moreover,we roughly estimate the height of the forest using polarimetric SAR data. |
