Analysis of Security Imaging Method for Walking Human Screening With Single Channel Synthetic Aperture Radar

IEEE Access, 2019
In this paper, a security screening imaging method for walking human with single channel synthetic aperture radar (SAR) technology is proposed. According to the theory of SAR imaging, the imaging response for each single echo of the three dimensional (3D)

Surface‐State Controls on Dust Emission Variability in Lower Mesopotamia and Kuwait Using Field and Multi‐High‐Resolution Satellite Data

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 9, September 2026.
Abstract Aeolian dust strongly influences climate, air quality, and biogeochemical cycles, yet identifying source areas and determining their surface‐state controls remain challenging. We focus on lower Mesopotamia and Kuwait, a globally significant dust source region where surface characteristics of dust sources remain poorly understood through ...

Resolution Equation for SAR Systems Synthesizing Circular Aperture

IEEE Access
The resolution of a synthetic aperture radar (SAR) system depends not only on the operating frequency range of a radar but also on the geometry. A radar system operating at MHz frequencies facilitates SAR resolution to the meter (m) level with a linear ...

Remote Sensing Hydrology Revisited: Advances, Persistent Challenges, and a Science‐Driven Agenda for the Next Decade

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract In the WRR 50th Anniversary Special Collection, Lettenmaier et al. (2015, https://doi.org/10.1002/2015WR017616) provided a timely account of how satellite remote sensing evolved from a niche capability in hydrology into a mainstream driver of hydrologic discovery, as the community shifted from imagery toward validated Earth Observation (EO ...

Synthetic-Aperture Radar Radio-Frequency Interference Suppression Based on Regularized Optimization Feature Decomposition Network

Remote Sensing
Synthetic-aperture radar (SAR) can work in all weather conditions and at all times, and satellite-borne radar has the characteristics of short revisiting period and large imaging width.

Satellite‐Based Fishing Fleet Tracking: A New Foundation for Fisheries Science and Management

Fish and Fisheries, Volume 27, Issue 5, Page 1134-1150, September 2026.
ABSTRACT Satellite‐based vessel‐tracking technologies have ushered in a new era for monitoring fishing activity at scale. By combining artificial intelligence (AI) methods with remotely‐sensed data, researchers can now detect, classify and analyse fishing behaviour across vast and previously unobservable ocean regions.

Floods From Space: How Remote Sensing, AI, and Cloud Platforms Are Reshaping Disaster Risk Reduction

Journal of Flood Risk Management, Volume 19, Issue 3, September 2026.
ABSTRACT Flooding remains one of the most damaging climate‐related hazards globally, yet flood remote sensing has historically developed largely along sensor‐specific pathways. This review addresses the need for a systematic and decision‐oriented synthesis of how space‐borne remote sensing has evolved toward integrated flood monitoring and disaster ...

Comparative Analysis of Urban Flood Mapping Using Sentinel‐1 SAR Imagery and Machine Learning

Journal of Flood Risk Management, Volume 19, Issue 3, September 2026.
ABSTRACT Flood mapping using remote sensing data has the potential to play a crucial role in monitoring and assessing flood events, particularly in urban environments, where complex infrastructure creates significant challenges. While Synthetic Aperture Radar (SAR) has promising potential for flood mapping, current methods struggle in the urban ...
