Aliasing in Near-Field Array Ambiguity Functions: a Spatial Frequency-Domain Framework

Gilles Monnoyer, Jérôme Louveaux, Laurence Defraigne +2

Next-generation communication and localization systems increasingly rely on extremely large-scale arrays (XL-arrays), which promise unprecedented spatial resolution and new functio…

Resolution-Aliasing Trade-off in Near-Field Localisation

Baptiste Sambon, Gilles Monnoyer, Luc Vandendorpe +1

Extremely Large-scale MIMO (XL-MIMO) systems operating in Near-Field (NF) introduce new degrees of freedom for accurate source localisation, but make dense arrays impractical. Spar…

Point Target Near-Field Bistatic Imaging: Chirp-Based Aliasing Analysis

Baptiste Sambon, Gilles Monnoyer, Claude Oestges +1

This paper presents a chirp-based framework for characterising aliasing in a bistatic Near-Field (NF) imaging system equipped with multidimensional antenna arrays. Extending monost…

Chirp-Based Aliasing Analysis of Arrays in the Spherical Wavefront Regime

Gilles Monnoyer, Laurence Defraigne, Baptiste Sambon +2

In antenna arrays, wave propagation modeling based on Euclidean principles is typically represented by steering vectors or signals. This paper provides a new, chirp-based, interpre…

Electromagnetic Modelling of Extended Targets in a Distributed Antenna System

Baptiste Sambon, François De Saint Moulin, Guillaume Thiran +2

Traditional radar and integrated sensing and communication (ISAC) systems often approximate targets as point sources, a simplification that fails to capture the essential scatterin…
