星载宽幅SAR干涉数据处理研究

Research on Scan SAR Interferometry Data Processing

结合ScanSAR的工作原理和特点,提出了分条带处理的方法,分析了ScanSAR数据处理的关键,对比分析叠片式条带拼接和配准加权拼接两种方法,提出了改进的配准加权方法,并用实验证明了本文提出的分条带处理方法和改进的配准加权方法的可行性和可靠性,为ScanSAR干涉测量的进一步研究提供了科学参考。

Combining with the working principle and characteristics of the Scan SAR,this paper proposed a sub-bands processing method,and analyzed the key points of the data processing of the Scan SAR.Compared laminated strip mosaicing with the method of coregistering and weighted strip mosaicing,the paper proposed a new improved method.And then,this paper illustrated the feasibility and reliability of sub-bands processing and the improved method of coregistering and weighted strip mosaicing by experiments,and provided a important scientific reference for the further study of Scan SAR interferometry.
