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 ...

The First Results of Ionospheric Skywave Propagation Experiment Over Taiwan
Radio Science, Volume 61, Issue 1, January 2026.Abstract An ionospheric over‐the‐horizon propagation experiment was carried out in Taiwan to investigate characteristics of ionospheric F layer skywave propagation at frequencies 4–12 MHz. Experimental results show that there are prominent diurnal variations in the incident angle, virtual height and plasma frequency at reflection height, which are ...

An LFM-Based Semiblind Synchronization Method for Bistatic Radar Imaging
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingBistatic radar provides an additional degree of freedom in the observing geometry for imaging by using a spatially separated transmitter and receiver. This capability allows the capture of scattering phenomena at various bistatic sensing angles, which ...

Target Coordinates Estimation by Passive Radar with a Single non-Cooperative Transmitter and a Single Receiver [PDF]
Journal of Communications Software and Systems, 2020 Passive radar is a bistatic radar that detects and tracks targets by processing reflections from non-cooperative transmitters. Due to the bistatic geometry for this radar, a target can be localized in Cartesian coordinates by using one of the following ...

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 ...
