Evaluation of Sentinel-1 Interferometric SAR Coherence efficiency for Land Cover Mapping
In this study, the capabilities of Interferometric Synthetic Aperture Radar (InSAR) time series data and machine learning have been evaluated for land cover mapping in Iran. In this way, a time series of Sentinel-1 SAR data (including 16 SLC images with approximately 24 days time interval) from 2018 to 2020 were used for a region of Ahvaz County located in Khuzestan province. Using InSAR proces...
متن کاملDeformation monitoring using Sentinel-1 SAR data
This paper describes the data processing and analysis procedure implemented by the authors to analyse Sentinel-1 data. The procedure is an advanced Differential Interferometric SAR (DInSAR) technique that generates deformation maps and time series of deformation from multiple SAR images acquired over the same site. The second part of the paper illustrates the results of the procedure. The first...
متن کاملCalibration of Dual Polarimetric C-band Sar Data: a Possible Approach for Sentinel-1
In this paper we discuss the radiometric calibration of dual polarimetric Synthetic Aperture Radar (SAR) data. The polarimetric distortion model of a dualpol SAR includes four calibration complex parameters: the cross-talk on transmit, the receiving channel imbalance and two receiving cross-talks. While these parameters can be estimated in a full-pol system using distributed targets with reflec...
متن کاملCombining disparate data sources for improved poverty prediction and mapping
More than 330 million people are still living in extreme poverty in Africa. Timely, accurate, and spatially fine-grained baseline data are essential to determining policy in favor of reducing poverty. The potential of "Big Data" to estimate socioeconomic factors in Africa has been proven. However, most current studies are limited to using a single data source. We propose a computational framewo...
متن کاملThe Sentinel-1 C-SAR Instrument Design & Performance
The ESA Sentinels constitute the first series of operational satellites responding to the Earth Observation needs of the EU-ESA Global Monitoring for Environment and Security (GMES) programme. The GMES space component relies on existing and planned space assets as well as on new complementary developments by ESA. This paper describes the Sentinel-1 mission, an imaging synthetic aperture radar (...
