In September 2019, the research icebreaker Polarstern started the largest multidisciplinary Arctic expedition to date, the MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) drift experiment. Being moored to an ice floe f

The Getz region of West Antarctica is losing ice at an increasing rate; however, the forcing mechanisms remain unclear. Here we use satellite observations and an ice sheet model to measure the change in ice speed and mass balance of the drainage basi

Non-Linear Modeling of Detectability of Ship Wake Components in Dependency to Influencing Parameters Using Spaceborne X-Band SAR
Autor: Björn Tings

Volume 13
Issue 2
Pages: 165
Remote Sensing, Vol 13, Iss 165, p 165 (2021)
The detection of the wakes of moving ships in Synthetic Aperture Radar (SAR) imagery requires the presence of wake signatures, which are sufficiently distinctive from the ocean background. Various wake components exist, which constitute the SAR signa

Potential for phase-based surface moisture estimation with C-band SAR data
Autor: Gomba, G., Zan, F., Palmisano, D., Francesco Mattia, Satalino, G.
Publikováno v: Scopus-Elsevier
Soil moisture estimation with synthetic aperture radar (SAR) images is currently based on the amplitude of backscattered signal. However, there are evidences that soil or vegetation moisture can influence the SAR interferometric phase (InSAR), in fac

Recovering unambiguous differential ionospheric phase screens
Autor: De Zan, Francesco, Gomba, Giorgio, Saporta, Paloma, Navarro Sanchez, Victor Diego
Synthetic aperture radar interferograms are affected by ionospheric disturbances. The split-spectrum method exploits the peculiar propagation of the radar waves through the ionosphere and recovers a phase screen that can be used to correct the interf

Long Term Geodetic Monitoring Using Active C-Band Radar Transponders And Sentinel-1 - First Results
Autor: Eineder, Michael, Gisinger, Christoph, Brcic, Ramon, Gruber, Thomas, Oikonomidou, Xanthi, Heinze, Markus
Reliable and accurate long term geodetic monitoring with SAR requires the installation of either passive corner reflectors or, alternatively smaller active devices. We report our first results using novel off-the-shelf transponders or electronic corn

Comments on 'Influence of the Statistical Properties of Phase and Intensity on Closure Phase'
Autor: De Zan, Francesco, Rocca, Fabio, Ferretti, Alessandro, Lopez Dekker, Paco, Eineder, Michael
Publikováno v: IEEE Transactions on Geoscience and Remote Sensing, 59(7)
A recent publication claims that closure phases in SAR interferometry bear no relationship to physical changes of the scatterer, but only to the statistical properties of the averaged pixels. We disprove this claim with a simple counterexample and re

Traditionally, sea level is observed at tide gauge stations, which usually also serve as height reference stations for national leveling networks and therefore define a height system of a country. One of the main deficiencies to use tide gauge data f
