Multipath Reflectivity Estimation in Urban Environments for Synthetic Aperture Radar Images
, 2010 Synthetic Aperture Radar (SAR) images a target region reflectivity function in the multi-dimensional spatial domain of range and cross-range. SAR synthesizes a large aperture radar in order to achieve a finer azimuth resolution than the one provided by ...

Importance of seasonal and annual layers in controlling backscatter to radar altimeters across the percolation zone of an ice sheet [PDF]
, 2006 Radar altimeters are one of the main tools for measuring elevation changes across the Antarctic and Greenland ice sheets and larger ice caps. A ground-based radar was deployed in autumn 2004 and spring 2006 in the percolation zone of the Greenland Ice ...

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.Silicon nitride samples were slip cast using yttrium oxide–aluminum oxide and ytterbium oxide sintering aids to fabricate plates with up to 40% porosity and compare them to a fully dense commercial standard. Silicon nitride plates were tested with an oxyacetylene torch to investigate changes in front and back face temperature, spectral emissivity ...

Fundamental aspects of netted radar performance
, 2010 Netted radar employs several spatially distributed transmitters and receivers for information retrieval. This system topology offers many advantages over traditional monostatic and bistatic systems which use a single transmitter and a single receiver ...

From Palestine Ally to Zionist Partner: India‐Israel Relations, 2014–2025
Middle East Policy, Volume 33, Issue 2, Page 156-174, Summer 2026.Abstract India's pro‐Palestinian diplomatic posture, which held for nearly 70 years, has been transformed within a single decade of rule by the Hindu nationalist Bharatiya Janata Party (BJP), turning New Delhi into one of Israel's most consequential Asian partners. This shift has narrowed the coalition supporting the Palestinian cause.

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract Drained and cultivated grasslands on peat soils behave as a significant source of greenhouse gasses by oxidation. However, the lack of empirical estimates of carbon losses from peatlands with adequate spatial and temporal resolution has forced researchers to rely on process‐based model approximations to make quantitative, regional‐ or national‐
