Abstract:

Traditional radar and integrated sensing and communication (ISAC) systems often approximate targets as point sources, a simplification that fails to capture the essential scattering characteristics for many applications. In a first part, this presentation outlines a novel electromagnetic (EM)-based framework to accurately model the near-field (NF) scattering response of extended targets, which is then applied to three canonical shapes: a flat rectangular plate, a sphere, and a cylinder. Our new framework, validated by measurements, directly highlights not only the relationships between the well-known radar equation (used in sensing models) and the Geometrical Optics (GO) approximation (used in ray-tracing and geometry-based models, such as 3GPP), but also the limitations of those approaches. Building on our modeling work, the second part analyzes the influence of bandwidth, carrier frequency, target curvature and range on the localization performance. A comparative analysis between extended and point-target models shows that, as the target size increases or becomes flatter, the point-target model introduces estimation errors owing to model mismatch. Operational zones where the point abstraction remains valid and where it breaks down are finally identified.

Bio:

Claude Oestges received the Electrical Engineering degree and the PhD degree in Applied Science from the Université catholique de Louvain (UCLouvain, Louvain-la-Neuve, Belgium), in 1996 and 2000, respectively. From 1996 to 2000, he was an Assistant Lecturer with the Microwave Laboratory UCLouvain, with lectures in electromagnetics, wireless communications and microwave engineering. His doctoral research dealt with propagation models and performance prediction methods for LEO satellite networks. In 1997, he spent two months at the Centre for Communication Systems Research, University of Surrey (UK). He was also involved in the European COST 255 Action “Radiowave propagation modeling for new SatCom services at Ku-band and above”.

From January to December 2001, Claude Oestges joined, as a post-doctoral scholar, the Smart Antennas Research Group (Information Systems Laboratory) of Stanford University (California, USA). He was involved in the development of MIMO multipolarized channel models for broadband wireless access in the field of G2 MMDS technology (with Sprint, Inc.).

From October 2001 to September 2005, Claude Oestges was a post-doctoral fellow of the Belgian National Science Foundation (Fonds de la RechercheScientifique, FRS-FNRS). Meanwhile, he carried out several short-term missions at Stanford University, and took part in COST 273 “Towards mobile broadband multimedia networks”, in NEWCOM Network of Excellence and in the IEEE 802.11 Standardization Working Group on “Multiple antenna channel modeling”. From October 2005 to October 2014, he was Associate Professor at UCLouvain and FRS-FNRS Senior Research Associate.

Since October 2014, Claude Oestges is Professor at UCLouvain and FRS-FNRS Honorary Senior Research Associate. His research interests cover wireless and satellite communications, with a focus on the propagation channel and its impact on system performance. His present activity concerns multi-dimensional channel modeling for wireless communications, including MIMO and cooperative networks, UWB systems and satellite systems. He was chairing the Working Group on “Reference channel modeling” in COST 2100 “Pervasive Mobile & Ambient Wireless Communications” and the Working Group on “Radio Channels” in COST IC1004 “Cooperative Radio Communications for Green Smart Environments “. He was also active in NEWCOM# Network of Excellence and was the Chair of COST CA15104 known as IRACON.

At the Louvain School of Engineering, Claude Oestges is teaching various courses and projects in physics, electrical circuits, propagation, and wireless communications. He was also head of the Electrical Engineering Degree Committee from 2015 to 2021.

Claude Oestges is a Fellow of the IEEE. He previously served in the Board of Directors of the European Association on Antennas and Propagation (EurAAP), and as Associate Editor for the IEEE Transactions on Antennas and Propagation and on Vehicular Technology. He is the author or co-author of four books and more than 200 papers in international journals and conference proceedings. He was the recipient of the IET Marconi Premium Award in 2001 and of the IEEE Vehicular Technology Society Neal Shepherd Award in 2004 and 2013.
