Quantitative estimation of sentinel-1A interferometric decorrelation using vegetation index

Frontiers in Earth Science, 2022
Sentinel-1A data are widely used in interferometric synthetic aperture radar (InSAR) studies due to the free and open access policy. However, the short wavelength (C-band) of Sentinal-1A data leads to decorrelation in numerous applications, especially in

Experimental synthesis of partially coherent beam with controllable twist phase and measuring its orbital angular momentum

Nanophotonics, 2021
Twist phase is a nontrivial second-order phase that only exists in a partially coherent beam. Such twist phase endows the partially coherent beam with orbital angular momentum (OAM) and has unique applications such as in super-resolution imaging. However,

Numerical Modeling of Nearshore Wave Transformation and Breaking Processes in the Yellow River Delta with FUNWAVE-TVD Wave Model

Journal of Marine Science and Engineering, 2023
The presence of wave coherence, which contributes to the inhomogeneity of wave characteristics and significantly affects wave processes over nearshore regions of the Yellow River Delta (YRD), was simulated and analyzed in this study.

Phase-Space Decoherence: a comparison between Consistent Histories and Environment Induced Superselection [PDF]

, 1993
We examine the decoherence properties of a quantum open system as modeled by a quantum optical system in the Markov regime. We look for decoherence in both the Environment Induced Superselection (EIS) and Consistent Histories (CH) frameworks.

Collective decision-making on triadic graphs [PDF]

, 2020
Many real-world networks exhibit community structures and non-trivial clustering associated with the occurrence of a considerable number of triangular subgraphs known as triadic motifs.

Reconstruction of longitudinal distributed incoherent sources [PDF]

, 1996
We describe measurement of the degree of coherence induced by a random light source distributed along the longitudinal z axis. If this degree of coherence is measured only between all the in-plane pairs of points placed along the radial lines it is ...

Long Term Interferometric Temporal Coherence and DInSAR Phase in Northern Peatlands

Remote Sensing, 2020
Peatlands of northern temperate and cold climates are significant pools of stored carbon. Understanding seasonal dynamics of peatland surface height and volume, often referred to as mire breathing or oscillation, is the key to improve spatial models of ...
