Analysis of the performance of polarimetric PSI over distributed scatterers with Sentinel-1 data

International Journal of Applied Earth Observations and Geoinformation, 2023
Sentinel−1 (S1) data enables effective monitoring of displacements using persistent scatterer interferometry (PSI). S1 includes VV and VH polarization channels, allowing us to apply polarimetric techniques to PSI.

Non-linear phase linking using joined distributed and persistent scatterers

, 2022
We describe a python package for nonlinear phase linking of full resolution SAR images using both distributed and persistent scatterers. In the workflow, the first step is to find for each pixel the set of self-similar pixels in order to identify ...

Effective Scatterer Diameter Estimates for Broad Scatterer Size Distributions [PDF]

Ultrasonic Imaging, 2014
Acoustic form factors have been used to model the frequency dependence of acoustic scattering in phantoms and tissues. This work demonstrates that a broad range of scatterer sizes, individually well represented by Faran theory or a Gaussian form factor, is not accurately described by a single effective scatterer from either of these models ...

HIGH RESOLUTION DEFORMATION TIME SERIES ESTIMATION FOR DISTRIBUTED SCATTERERS USING TERRASAR-X DATA [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
In recent years, several SAR satellites such as TerraSAR-X, COSMO-SkyMed and Radarsat-2 have been launched. These satellites provide high resolution data suitable for sophisticated interferometric applications. With shorter repeat cycles, smaller orbital

An Adaptive Weighted Phase Optimization Algorithm Based on the Sigmoid Model for Distributed Scatterers

Remote Sensing, 2021
Distributed scatterers (DSs) have been widely used in the time series interferometric synthetic aperture radar technique, which compensates for the insufficient density of persistent scatterers (PSs) in nonurban areas. In contrast to PS, DS is vulnerable
