Building profile reconstruction using TerraSAR-X data time-series and tomographic techniques [PDF]

open access: yes, 2015
This work aims to show the potentialities of SAR Tomography (TomoSAR) techniques for the 3-D characterization (height, reflectivity, time stability) of built-up areas using data acquired by the satellite sensor TerraSAR-X.

Efficient SAR Raw Data Compression in Frequency Domain [PDF]

open access: yes, 1999
SAR raw data compression is necessary to reduce huge amounts of SAR data for a memory on board a satellite, space shuttle or aircraft and for later downlink to a ground station.

Visualization of Skewed Data: A Tool in R [PDF]

open access: yes, 2014
In this work we present a visualization tool specifically tailored to deal with skewed data. The technique is based upon the use of two types of notched boxplots (the usual one, and one which is tuned for the skewness of the data), the violin plot, the ...

Digital Beamforming and Traffic Monitoring Using the new FSAR System of DLR [PDF]

open access: yes, 2007
In November 2006 the first X-band test flight of DLR’s new FSAR system has been performed successfully and in February 2007 the first flight campaign has been conducted for acquiring experimental multi-channel data of controlled ground moving targets. In

Polarimetric bistatic SAR image coherence

open access: yes, 2022
Synthetic Aperture Radar (SAR) Coherent Change Detection (CCD) allows the detection of very small scene changes, such as from ground subsidence or vehicle tracks, with applications both civilian and military. This high sensitivity to small changes can mean that differences in collection geometry or in polarisation can lead to significant changes in ...

Change detection in SAR time-series based on the coefficient of variation

open access: yes, 2019
This paper discusses change detection in SAR time-series. Firstly, several statistical properties of the coefficient of variation highlight its pertinence for change detection. Then several criteria are proposed. The coefficient of variation is suggested
