8 Abstract 9 This paper focuses on different methods for estimating soil moisture in a Sahelian environment by comparing ENVISAT/ASAR and ground data 10 at the same spatial scale. The analysis is restricted to Wide Swath data in order to take advantage of their high temporal repetitivity (about 3–4 days) 11 corresponding to a moderate spatial resolution (150 m). On the one hand, emphasis is put...

Karia kentlerinden birisi olan Myndos, günümüzde Muğla ili, Bodrum ilçesi, Gümüşlük beldesi sınırları içerisinde yer almaktadır. Antik kentin hemen karşısında konumlanan Asar / Tavşan Adası, limanını korumak için oldukça önemli bir lokasyonda bulunur. Ada’da yapılan araştırmalar sonucunda ortaya çıkartılan yapı kalıntılarının bölümü, Klasik Dönem ve sonrasına tarihlendirilmektedir. Adası’nın gi...

The present study addresses the potential of Synthetic Aperture Radar (SAR) data for land cover classification in parts of Dandeli forested regions, Karnataka, India. a FCC has been generated from coherence and backscattering co-efficient images of ENVISATASAR data (HH polarizations) of 25 Sep 2006 and 30 Oct 2006. Similarly, ENVISAT-ASAR data (HH polarization) of 25 Sep 2006 along with IRS –P6...

The objective of this study is to get a better understanding of radar signal over irrigated wheat fields and to assess the potentialities of radar observations for the monitoring of soil moisture. Emphasis is put on the use of high spatial and temporal resolution satellite data (Envisat/ASAR and Formosat-2). Time series of images were collected over the Yaqui irrigated area (Mexico) throughout ...

Mapping volcanic flow deposits can be achieved by considering backscattering characteristics as a metric of surface roughness. In this study, we developed an approach to extract measure roughness from dual-band airborne Synthetic Aperture Radar (ASAR) data characterize and map various deposits—namely, debris avalanches, lahars, lava flows, pyroclastic density currents. We employed ASAR Indian S...

The results of an interferometric performance analysis for spaceborne parasitic SAR configurations are presented. The analysis includes errors due to limited SNR, block adaptive quantization, range and azimuth ambiguities, and geometric decorrelation for both flat surfaces and random volumes. Relative height accuracies for three spaceborne configurations with PALSAR, ASAR and TerraSAR-X as illu...

This paper presents a technique to detect oil spills in ENVISAT Advanced Synthetic Aperture Radar (ASAR) images using radar backscatter thresholding and logistic regression analysis. We developed and tested this technique using 4 Envisat ASAR images that were acquired many days after the M/T Solar I oil spill incident occurred on August 11, 2006 in Panay Gulf, southwest of Guimaras Island in Vi...

Technology scaling in microelectronics has reached limits that are resulting in increasing variation in component design and performance characteristics. Chips and systems comprising of such components are starting to exhibit a rise in process-induced failures and soft errors. Conventional design time solutions such as conservative guardbands to hide such variations are increasingly not viable ...
