分析了ScanSAR-Stripmap干涉测量的相位组成,指出其因非同步数据引起的特有相位项,并通过实验验证了该相位项的存在。提出一整套ScanSAR-Stripmap干涉测量方法,借助JPL开发的开源干涉测量软件ROI_PAC的相应模块实现干涉处理过程,重点解决了ScanSAR-Stripmap两种模式数据间的配准以及相干性的提高等问题。用EnvisatASAR数据验证了该方法的可行性。最后将实验结果同常规条带式干涉测量结果做了对比与分析,验证了该方法的正确性。 更多还原
【Abstract】 This study analyzes the main phase contributions of ScanSAR-Stripmap interferometry and further points out the special component caused by unsynchronized echoes, which is then verified in the experiment. The whole process of ScanSAR-Stripmap interferometry has been proposed and implemented with the help of relating modules of the Repeat Orbit Interferometry Package (ROI_PAC) developed by Jet Propulsion Laboratory (JPL). Coregistration and improvement of coherence are solved emphatically. Finally... 更多还原
