Focused Session at IRS 2026

Radar Systems for Space Situational Awareness and Spaceborne Earth Observation

The growing population of objects in Earth’s orbit has intensified the need for advanced radar systems to monitor near-Earth space. The rapid expansion of satellite constellations and the accumulation of orbital debris have significantly increased global interest in Space Situational Awareness (SSA), driving research into radar technologies for the detection, tracking, and characterization of space objects.

At the same time, continuous advances in spaceborne sensor technologies have led to a growing number of radar-based solutions for observing and monitoring the Earth’s surface from orbit, enabling a wide range of scientific, environmental, and security-related applications.

This session will showcase the latest advancements in active and passive radar systems for both Space Situational Awareness and spaceborne Earth observation. It will focus on innovative system architectures, state-of-the-art signal processing techniques, and results from real-world experiments and operational missions. Attendees will gain insight into how these developments address key technical challenges and support the increasing demands of both space surveillance and Earth monitoring.

Session Chair

Konrad JędrzejewskiKonrad Jędrzejewski, D.Sc., Ph.D., is a Professor at the Warsaw University of Technology (WUT), where he leads the Adaptive Information Processing Systems Team. He received his M.Sc. in Electronics and Telecommunications (1995) and Ph.D. in Electronics (2000), both with honors, from the Faculty of Electronics and Information Technology at WUT, and earned his D.Sc. in Electronics in 2014. From 2000 to 2019, he served as Assistant Professor at WUT and was promoted to Associate Professor in 2019. Professor Jędrzejewski has participated in numerous national and international R&D projects in the defense, security and telecommunications. He has served as project manager in several large-scale projects in the radar and navigation fields with many universities, research institutions and enterprises in Poland and abroad. He currently leads a national project aimed at building a radar technology demonstrator for Low-Earth Orbit (LEO) surveillance, and also leads work on behalf of WUT in an international project funded by the European Defence Agency. Since 2020, he has been an active member of NATO Science and Technology Organization (STO) Research Task Groups on Space Domain Awareness. He is also the lecturer in NATO STO Lecture Series in this area.
He is the author of over 120 scientific publications, including papers prestigious journals as IEEE Aerospace and Electronic Systems Magazine, IET Radar Sonar & Navigation, IEEE Transactions on Instrumentation and Measurement, Measurement (Elsevier), Metrology and Measurement Systems, International Journal of Microwave and Wireless Technology, Remote Sensing, Sensors, Journal of Clinical Medicine. He is co-author of three patents. His research interests encompass statistical and adaptive signal processing, radar signal processing, biomedical signal processing, machine learning, and A/D converters. His recent research has focused on passive radar systems for observing LEO space targets using terrestrial illuminators of opportunity. The findings from these studies have been presented at numerous leading international radar conferences, including multiple editions of both the IEEE Radar Conference and the IEEE International Radar Conference series. Notably, he received the Best Paper Award at the IEEE International Radar Conference 2023 in Sydney for the paper titled: “Passive Multistatic Localization of Space Objects Using LOFAR Radio Telescope.”
He has served as Chair (since 2023) and Vice-Chair (2019-2023) of the Poland Chapter of the IEEE Signal Processing Society. He is a member of the Polish Information Processing Society (PTI), a board member of the Polish Society for Measurement, Automatic Control and Robotics (POLSPAR), an expert for the National Center for Research and Development (NCBR), and Secretary of the Section of Microwaves and Radiolocation of the Committee of Electronics and Telecommunications of the Polish Academy of Sciences.
