InSAR Ground Deformation and Pumping Energy Consumption Reveal Urban Water Security

Water Resources Research, Volume 62, Issue 1, January 2026.
Abstract Water resource assessments are critical for ensuring water security (WS), particularly in rapidly urbanizing regions with increasing water demand and limited water monitoring capabilities. Earth observations and indirect indicators of surface and groundwater changes are valuable tools for developing such assessments.

Optimisation of Sparse Linear Arrays Based on Enhanced Differential Evolution Algorithm

IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.
To address the challenge of reducing the peak sidelobe level (PSLL) in linear sparse array antennas, a differential evolution (DE) algorithm that integrates feasible solution repair and dynamic subpopulation selection is proposed. ABSTRACT To address the challenge of reducing the peak sidelobe level (PSLL) in linear sparse array antennas, a ...

Spectrally Compatible Deceptive Jamming Waveform Design for Synthetic Aperture Radar Countermeasures

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper focuses on the design of synthetic aperture radar (SAR) deceptive jamming waveforms with spectrum‐compatible capability. By using the synthesised jamming waveform, successful deception against the hostile SAR system is demonstrated by generating false targets with high fidelity in both range and azimuth.

WFH: A Wideband Frequency Hopping‐Based Anti‐Jamming Navigation Signal Structure

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
Given the limitations of existing satellite navigation signals in antijamming performance amid growing environmental jamming, this paper proposes a navigation signal structure based on wideband frequency hopping (WFH) modulation to enhance both antijamming capability and measurement accuracy. It further introduces the nonstationary effective carrier‐to‐

Temporal Beta Diversity of Local Zooplankton Communities in Small Reservoirs is Associated With Hydrological Seasonality

Freshwater Biology, Volume 71, Issue 1, January 2026.
ABSTRACT The variation in local community structure over time—temporal beta diversity—is likely to depend on drivers similar to those used to explain spatial beta diversity. For example, in parallel with the expected relationship between geographic distance and spatial beta diversity, the longer the time between two sampling campaigns, the higher the ...

Talking About the Weather: The Feasibility of Using Very High‐Resolution Optical Satellite Imagery to Monitor Live and Stranded Cetaceans Around the UK and UK Overseas Territories

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Monitoring live and stranded cetaceans can be expensive and logistically challenging, resulting in knowledge gaps. Very high‐resolution (VHR) optical satellites are considered a potential solution to addressing some of these gaps. Despite success at detecting live and stranded cetaceans, satellites have only been trialed on restricted ...
