Locating a weak change using diffuse waves (LOCADIFF) : theoretical approach and inversion procedure [PDF]

, 2010
We describe a time-resolved monitoring technique for heterogeneous media. Our approach is based on the spatial variations of the cross-coherence of coda waveforms acquired at fixed positions but at different dates.

Quantification and compensation of temporal decorrelation effects in polarimetric SAR interferometry [PDF]

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
Temporal decorrelation is a critical issue for a successful Pol-InSAR inversion in case of repeat-pass SAR data, as provided by conventional satellite or airborne SAR systems. This paper proposes estimation and compensation of temporal decorrelation effects by using multi-baseline Pol-InSAR data.

New 9.9-GHz methanol masers [PDF]

, 2010
The Australia Telescope Compact Array (ATCA) has been used to make the first extensive search for the class I methanol masers at 9.9 GHz. In total, 48 regions of high-mass star formation were observed.

Generalized-Capon Method for Diff-Tomo SAR Analyses of Decorrelating Scatterers

Remote Sensing, 2019
In synthetic aperture radar (SAR) remote sensing, Differential Tomography (Diff-Tomo) is developing as a powerful crossing of the mature Differential SAR Interferometry and the emerged 3D SAR Tomography.

MT-INSAR LANDSLIDE MONITORING WITH THE AID OF HOMOGENEOUS PIXELS FILTER [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
SAR interferograms are often contaminated by random noises related to temporal decorrelation, geometrical decorrelation and thermal noises, which makes the fringes obscured and greatly decreases the density of the coherent target and the accuracy of ...

A statistical gap-filling method to interpolate global monthly surface ocean carbon dioxide data [PDF]

, 2015
We have developed a statistical gap-filling method adapted to the specific coverage and prop-erties of observed fugacity of surface ocean CO2(fCO2). We have used this method to interpolate the Sur-face Ocean CO2Atlas (SOCAT) v2 database on a 2.5832.58 ...

Widefield multiphoton and temporally decorrelated multifocal multiphoton microscopy

Optics Express, 2000
We demonstrate a widefield multiphoton microscope and a temporally decorrelated, multifocal, multiphoton microscope that is based on a high-efficiency array of cascaded beamsplitters. Because these microscopes use ultrashort pulse excitation over large areas of the sample, they allow efficient use of the high-average power available from modern ...

High quality InSAR data linked to seasonal change in hydraulic head for an agricultural area in the San Luis Valley, Colorado [PDF]

, 2011
In the San Luis Valley (SLV), Colorado legislation passed in 2004 requires that hydraulic head levels in the confined aquifer system stay within the range experienced in the years 1978–2000.
