ITR: Post-Processing Strategies for Radar Differential Interferometry

EAR-0219293肖恩·M. Buckley卫星雷达干涉测量法（干涉合成孔径雷达）提供了比任何其他传统大地测量技术更高分辨率和更大空间覆盖范围的地表变形测量，并已迅速发展成为测量与自然和人为灾害有关的变形的关键工具。 干涉合成孔径雷达测量的例行制作是干涉合成孔径雷达处理软件普遍可用的结果，每个软件包产生相同的通用最终产品-差分干涉图。 虽然最近的干涉合成孔径雷达研究已考虑综合使用数十幅干涉图来揭示复杂和微妙的地表变形，但干涉合成孔径雷达地球科学界还没有现成的后处理软件包。 该项目涉及干涉合成孔径雷达后处理软件包的研究和开发，该软件包采用了当前干涉合成孔径雷达软件所缺少的三种一般性策略：多个卫星轨迹的镶嵌以进行完整的表面位移测量、干涉图叠加以减少噪声、以及干涉合成孔径雷达时间序列分析以测量连续的非均匀变形。 该软件是模块化的，用C和Fortran编写，从一系列基于Unix的shell脚本调用，一般独立于用于生成差分干涉图的干涉合成孔径雷达软件开发。 在需要处理器特定信息的情况下，该软件与喷气推进实验室ROI_PAC软件包集成。 后处理工具包的分发是通过GNU通用公共许可证。

EAR-0219293Sean M. BuckleySatellite radar interferometry (InSAR) provides earth-surface deformation measurements at finer resolution and greater spatial coverage than any other traditional geodetic technique and has quickly developed into a critical tool for measurement of deformation associated with natural and anthropogenic hazards. The routine production of InSAR measurements is a consequence of the general availability of InSAR processing software with each package producing the same general final product - the differential interferogram. Although recent InSAR research has considered the ensemble use of tens of interferograms to reveal complex and subtle surface deformation, a post-processing software package is not readily available to the InSAR geoscience community. This project involves the research and development of an InSAR post-processing software toolkit employing three general strategies missing from current InSAR software: mosaicking of multiple satellite tracks for complete surface displacement measurement, interferogram stacking for noise reduction, and InSAR time-series analysis for measurement of continuous, non-uniform deformation. The software is modular, coded in C and Fortran, called from a series of Unix-based shell scripts and developed generally independent of the InSAR software used to generate the differential interferograms. Where processor-specific information is required, the software is integrated with the Jet Propulsion Laboratory ROI_PAC software package.
