Distributed Scatterer Processing Based on Binary Partition Trees with Multi-Baseline PolInSAR Data

open access: yesRemote Sensing, 2022
Distributed scatterers (DSs) are necessary to increase point density in multi-temporal InSAR (MT-InSAR) monitoring. The identification of homogeneous pixels (HPs) is the first and key step for DS processing to overcome the low signal-to-noise ratio ...

Directional Bandgap Analysis in Phononic Crystal with Rectangular Super Cell Structure [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences, 2022
Phononic crystals have promising applications in the field of elastic waves and to attenuate the vibrations with their extraordinary feature of stop bands also known as bandgaps. Due to periodicity in structure, the wave in certain band of frequencies is

Assessment of the accuracy among the common persistent scatterer and distributed scatterer based on SqueeSAR method

open access: yes, 2022
SqueeSAR, also known as advanced time-series interferometric synthetic aperture radar (ATS-InSAR) method, is a significant improvement of conventional persistent scatterer InSAR (PSInSAR), whereby the concepts of distributed scatterer (DS) and persistent

An Adaptive Phase Optimization Algorithm for Distributed Scatterer Phase History Retrieval

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
The multitemporal interferometric synthetic aperture radar (InSAR) technique based on distributed scatterers (DSs) has been widely applied in high-precision deformation measurements, which compensates for the drawback that the persistent scatterer InSAR ...

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

open access: yesInternational 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.

Electron distribution in nonlinear Compton scattering [PDF]

open access: yesJournal of Physics: Conference Series, 2012
Based on quantum theory, we investigate the distribution of the electrons scattered in nonlinear Compton effect by an electromagnetic plane wave. Deviations of the final electron momentum from its initial value are solely due to quantum effects. The monochromatic case, examined in detail, reveals features of the electron distribution, useful in the ...
