(Dept. of Surveying Engineering, Southwest Jiaotong University, Chengdu 610031, China ) Abstract: As the fourth part of the tutorial, the paper will introduce and discuss the data reduction procedures and the key algorithms in InSAR. The primary data processing procedures are also represented in ...
[8], who made a stacking of a time series of interferograms to enhance the signal-to-noise ratio of the crustal strain signal relative to atmospheric and orbital errors. After that, various InSAR time series analysis methods...
As the incident angle decreases, the image's echo signal is enhanced, resulting in brighter pixels37. This unique imaging method makes the radar images highly susceptible to displaying anomalies. When the slope substantially changes, illuminating the back slope is difficult for the beam, consequently...
但此处值得注意的是,最新研究发现,尽管利用短时间间隔的多视SAR数据会削弱失相干噪声,但也会伴随“衰落”信号的出现,又称作Fading Signal[69]。该信号的特性不同于失相干引起的随机噪声,它会引入系统偏差并随时间衰减。以上3种策略受限于研究区现有的SAR数据条件,其可行性和普适性不强。④应用相位优化方法。该方法...
The above method can transform the spatial reference frame of InSAR data to the same Ordos-fixed reference frame as the GNSS velocities, and it can effectively eliminate long-wavelength signal errors (Hussain et al., 2016a, Hussain et al., 2016b, Weiss et al., 2020) while preserving the ...
