SAC-Controlled RIS-Assisted Monopulse Radar for Multipath-Robust Vital-Sign Localization
Jafar Norolahi, Alireza Vahid
Contactless radar sensing offers a promising approach to continuous vital-sign monitoring. However, indoor multipath can distort direction estimates and generate ghost responses. T…
Learning-Based Beam Adaptation for Active/Passive-Aware Monopulse ISAC with Leakage Suppression
Jafar Norolahi, Alireza Vahid
This paper proposes a learning-based beam adaptation framework for active/passive-aware monopulse integrated sensing and communication (ISAC) with spatial leakage suppression. A si…
Secure Pseudonymetry with DSSS Watermarking for LEO Satellites
Nisanur Camuzcu, Alireza Vahid
Low-Earth-orbit (LEO) constellations offer dense signals of opportunity (SOP) for positioning, navigation, and timing (PNT) without dedicated navigation infrastructure. However, us…
Starlink Beacons for Passive LEO-Aided 9D Navigation
Nisanur Camuzcu, Tiep M. Hoang, Alireza Vahid
Global Navigation Satellite Systems (GNSS) underpin positioning, navigation, and timing (PNT), yet their low-power signals are easily blocked or disrupted, leaving gaps in PNT avai…
