| 摘 要： | 针对PALSAR Level 1.1数据,研究使用NASA/JPL提供的开源干涉软件包ROI_PAC Version 3.0提取DEM.ROI_PAC的目前版本只能处理Level 1.0数据,因此,文章在分析了ROI_PAC软件包处理流程的基础上,提出处理Level 1.1数据的方法,并用PALSAR Level 1.1数据对该方法做了验证.干涉重建DEM与参考DEM的对比结果表明,二者的差异均值为0.27 m,标准差为±9.24 m,80%像元点的高程误差在±10 m以内. |

| Abstract: | In the past decades,researchers have successfully rebuilt the digital elevation model(DEM) using such Interferometric synthetic aperture radar data(InSAR) as SIR-C/X SAR and ERS1/2.As a new generation of synthetic aperture radar,Phased Array type L-band Synthetic Aperture Radar(PALSAR),which is onboard Advanced Land Observing Satellite(ALOS),works at a longer wave length-L band.Its penetrating depth is deeper than the radars that work at C band.Thus it has advantages in the construction of DEM.However,there... |
