Modified Multi-Mode Target Tracker for High-Frequency Surface Wave Radar
Remote Sensing, 2018 In high-frequency surface wave radar (HFSWR), part of the radiation signal inevitably propagates upward and illuminates the target through the ionosphere due to the poor controllability of the antenna’s vertical pattern.

Uncertainty Propagation From Radio Occultation Profiles to Aggregated Atmospheric Gridded Fields
Earth and Space Science, Volume 13, Issue 1, January 2026.Abstract Radio occultation is a well‐established remote sensing method that provides reliable estimates of atmospheric profiles of diverse variables, including temperature and pressure. However, as with all indirect methods, radio occultation has some inherent systematic and random error effects, which lead to observational uncertainties.

An extension of the RiMAX multipath estimation algorithm for ultra-wideband channel modeling
EURASIP Journal on Wireless Communications and Networking, 2018 This work presents an extension of the high-resolution RiMAX multipath estimation algorithm, enabling the analysis of frequency-dependent propagation parameters for ultra-wideband (UWB) channel modeling. Since RiMAX is a narrowband algorithm, it does not
