High-Quality Pixel Selection Applied for Natural Scenes in GB-SAR Interferometry
Remote Sensing, 2021 Phase analysis based on high-quality pixel (HQP) is crucial to ensure the measurement accuracy of ground-based SAR (GB-SAR). The amplitude dispersion (ADI) criterion has been widely applied to identify pixels with high amplitude stability, i.e ...

基于InSAR数据分析四川盆地南部长宁页岩气区块地表形变场基本特征
Dizhen xuebao, 2022 近年来随着我国页岩气大规模开采，四川盆地南部活动构造相对稳定的地区出现了一系列微震和有感地震，甚至是破坏性地震。这些地震是否为工业开采所诱发，目前已有研究从时空相关性给出了一些统计推断，本文则从形变观测角度分析页岩气开采能否产生可以检测到的地面形变，以揭示形变信息与页岩气开采的关系，尝试为页岩气开采提供有效的监测手段。基于长波ALOS-2卫星雷达数据对长宁页岩气区块近两三年内的InSAR地表形变展开探测，检测页岩气大规模生产可能造成的地面形变及其基本特征，同时使用Sentinel ...
