Using InSAR Coherence to Map Stand Age in a Boreal Forest

Remote Sensing, 2012
The interferometric coherence parameter γ estimates the degree of correlation between two Synthetic Aperture Radar (SAR) images and can be influenced by vegetation structure. Here, we investigate the use of repeat-pass interferometric coherence &

Demonstration of Spaceborne Multi-static SAR Tomography and Forest Height Estimation

Leida xuebao
Synthetic Aperture Radar Tomography (TomoSAR), by virtue of its three-dimensional (3D) resolution capability, can be used to study the 3D structure of semitransparent targets, such as forests, icebergs, and snowpacks.

Anomalous Viscosity of the Quark-Gluon Plasma

, 2014
The shear viscosity of the quark-gluon plasma is predicted to be lower than the collisional viscosity for weak coupling. The estimated ratio of the shear viscosity to entropy density is rather close to the ratio calculated by N = 4 super Yang-Mills ...

Detecting single-trial EEG evoked potential using a wavelet domain linear mixed model: application to error potentials classification

, 2015
Objective. The main goal of this work is to develop a model for multi-sensor signals such as MEG or EEG signals, that accounts for the inter-trial variability, suitable for corresponding binary classification problems. An important constraint is that the

StaMPS Improvement for Deformation Analysis in Mountainous Regions: Implications for the Damavand Volcano and Mosha Fault in Alborz

Remote Sensing, 2015
Interferometric Synthetic Aperture Radar (InSAR) capability to detect slow deformation over terrain areas is limited by temporal decorrelation, geometric decorrelation and atmospheric artefacts.

High frame-rate cardiac ultrasound imaging with deep learning

, 2018
Cardiac ultrasound imaging requires a high frame rate in order to capture rapid motion. This can be achieved by multi-line acquisition (MLA), where several narrow-focused received lines are obtained from each wide-focused transmitted line.

Spaceborne Polarimetric SAR Interferometry: Performance Analysis and Mission Concepts

EURASIP Journal on Advances in Signal Processing, 2005
We investigate multichannel imaging radar systems employing coherent combinations of polarimetry and interferometry (Pol-InSAR). Such systems are well suited for the extraction of bio- and geophysical parameters by evaluating the combined scattering ...
