A Modified Hierarchical Vision Transformer for Soil Moisture Retrieval From CYGNSS Data
Water Resources Research, Volume 62, Issue 1, January 2026.Abstract This research introduces a new deep learning (DL) framework, multi‐head self‐attention‐aided vision Transformer (MSA‐ViT), for soil moisture (SM) retrieval using Cyclone Global Navigation Satellite System (CYGNSS) data. We first assess the sensitivity of CYGNSS reflectivity (Γ) $({\Gamma })$ to SM, demonstrating a strong physical linkage ...

IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.The study presents the design and development of a plasma‐based antenna array system for the UHF band. The system features an omnidirectional plasma antenna as its active radiator, a novel approach that has not been previously explored. Surrounding plasma reflectors form a reconfigurable array around the monopole plasma antenna for beam shaping and ...

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This work proposes a micro‐Doppler‐assisted particle‐filtering track‐before‐detect (mD‐PF‐TBD) algorithm with a variable‐particle mechanism to robustly track UAVs in passive radar systems, particularly when they enter the Doppler‐blind zone (DBZ). As the target Doppler frequency approaches zero, the algorithm adaptively reallocates particles towards ...
