Hybrid polarimetry inverse synthetic aperture radar

open access: yesIET Radar, Sonar & Navigation
The inverse synthetic aperture radar (ISAR) system exploits the movement of the target to form its high‐resolution image. Further, the multi‐polarisation acquisition in ISAR collects additional information on the target's scattering properties and ...

Exact spectrum of non-linear chirp scaling and its application in geosynchronous synthetic aperture radar imaging

open access: yesThe Journal of Engineering, 2013
Non-linear chirp scaling (NLCS) is a feasible method to deal with time-variant frequency modulation (FM) rate problem in synthetic aperture radar (SAR) imaging.

Quantifying the Influence of Vegetation on Net Snow Accumulation Across Elevations, Aspects and During Years With High and Low Snowfall

open access: yesEcohydrology, Volume 19, Issue 1, January‐February 2026.
ABSTRACT Seasonal snowmelt from forested mountain catchments is the primary water source for both people and ecosystems in the western United States. As changes in climate and vegetation alter relationships between snow accumulation and water availability, quantifying the influence of ecosystem structure on snow water resources is a critical challenge.

EXPERIENCE OF RADAR DATA PROCESSING FOR GEOGRAPHIC MAPPING

open access: yesInterCarto. InterGIS, 2014
New synthetic aperture radar (SAR) systems suggest new potentials for the environmental studies and mapping due to high spatial resolution, various beam modes and the full polarization mode. Current level of imaging radar development together with amount

Synthesis to Design Spherical and Deformed Spherical Antenna Array Structures

open access: yesMicrowave and Optical Technology Letters, Volume 68, Issue 1, January 2026.
ABSTRACT Antenna array is a key component in various communication systems these days. Rather than various linear and planar array structures, antenna elements are strictly conformed to the curved‐shape surfaces they are mounted in conformal antenna arrays.

Using Sentinel‐1 and Sentinel‐2 to assess the role of soil water content and vegetation cover in mitigating wind erosion in cultivated organic soil

open access: yesVadose Zone Journal, Volume 25, Issue 1, January/February 2026.
Abstract Wind erosion is a major threat to organic soils under intensive agriculture, reducing their productivity and long‐term sustainability. Up to 2.5 cm of soil can be lost in a single storm. This study examined how soil water content and vegetation cover influence wind erosion in cultivated organic soils of the Montérégie region, Quebec, using ...

Free‐access geospatial data and machine learning deliver high‐resolution soil salinity maps in the Sonoran Basin and Range

open access: yesVadose Zone Journal, Volume 25, Issue 1, January/February 2026.
Abstract Soil salinity is a serious threat to crop productivity and is anticipated to increase in the coming decades, particularly in semi‐arid to arid agricultural regions. Accessible geospatial data and data mining techniques can enable high‐resolution mapping of soil salinity to improve predictions and soil management.
