Design and Reception Method of Code Shift Keying Signals With Power‐of‐Two Phase Intervals
IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.A novel approach for the design and reception of CSK signals with a phase interval mapping of power‐of‐two chips is proposed. This method is capable of significantly reducing the demodulation complexity while mitigating the intersymbol interference. ABSTRACT Precise point positioning (PPP) technology has garnered extensive attention for its ability to ...

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.This article proposes a feedback node aided distributed spoofing (FNA‐DS) system, enabling flexible implementation of distributed spoofing. Field experiments using a self‐developed distributed spoofing prototype validate the FNA‐DS system's effectiveness and expose limitations in existing direction of arrival based anti‐spoofing techniques.

A Satellite Drift Scan Approach for Establishing the Pointing Model of Radio Telescopes
Advances in Astronomy, Volume 2025, Issue 1, 2025.In the era of large satellite constellations, there are more than 1000 satellites in orbit. While the signals from these satellites may pose a risk of radio frequency interference (RFI) to radio telescopes, they also present a potential advantage by serving as high‐spatial‐density pointing references for radio telescopes.
