Raul Onrubia

Raul Onrubia is a researcher at the Universitat Politècnica de Catalunya (UPC), affiliated with the Passive Remote Sensing Group. He holds a PhD in GNSS-Reflectometry (2020) and specializes in radio frequency interference (RFI) mitigation, antenna array calibration, and microwave radiometry. His work focuses on advancing passive Earth observation technologies, particularly with the SMOS satellite mission and the Microwave Interferometric Reflectometer (MIR).

Education: BSc+5 in Telecommunications Engineering (2012), MSc+2 in Information and Communication Technologies (2014), both from UPC. His PhD research addressed RF hardware design for GNSS-Reflectometry instruments. He has contributed to airborne and spaceborne experiments, including the 3CAT-3/MOTS nanosatellite and the GEROS-ISS ocean altimetry project.

Research interests include RFI detection in microwave radiometry, dual-frequency GNSS-R applications (e.g., soil moisture, vegetation height), and instrument development for future space missions. He collaborates with institutions like NASA and the European Space Agency, and his work integrates signal processing, antenna design, and environmental data analysis.

Publications highlight innovations in RFI mitigation algorithms, interferometric techniques, and the retrieval of geophysical parameters from reflected GNSS signals. His contributions are critical for improving the accuracy of Earth observation systems amid growing RFI challenges.
