Foreword to the Special Issue on GNSS Reflectometry

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2016
The papers in this special section focus on Global Navigation Satellie System reflectometry(GNSS-R) which is defined as the use of digital signals—here signals from Global Navigation Satellite Systems (GNSS)—as sources of illumination in a bistatic radar system.

Modified GNSS-PIR and Initial Verifications From the Perspective of Altimetry

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
This article proposed a modified structure of global navigation satellite system (GNSS) pseudointerferometric reflectometry (GNSS-PIR). The combination of the direct and reflected signals at the front end was modified as the combination of their coherent

Comparison and Synergy of BPSK and BOC Modulations in GNSS Reflectometry

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Signals from global navigation satellite systems (GNSSs) have been advocated as opportunities for remote sensing of the Earth. In the multi-GNSS era, signals from different constellation, at different frequency, and under different modulation are ...

Diffusion‐Based Reconstruction of Western North Pacific Surface Winds From CYGNSS for Tropical Cyclone Analysis

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 10, October 2026.
Abstract Sea surface wind retrieval under extreme weather conditions is constrained by the sparse and irregular spatiotemporal sampling of Global Navigation Satellite System Reflectometry (GNSS‐R). This study presents a probabilistic wind field reconstruction framework for the Western North Pacific using Score‐Based Data Assimilation (SDA). A diffusion
