Doppler-Only Extended Target Tracking in a Distributed Antenna System
Baptiste Sambon, Gilles Monnoyer, Luc Vandendorpe +1
In modern radar and Integrated Sensing and Communication (ISAC) systems, the conventional point-scatterer assumption becomes increasingly inaccurate due to higher spatial resolutio…
G-iMUSIC: Greedy Iterative MUSIC Algorithms for Multi-Target DoA Estimation
Martin Willame, Gilles Monnoyer, François Horlin +1
This paper presents novel algorithms for multi-target direction-of-arrival (DoA) estimation in array signal processing. Although the maximum likelihood estimator (MLE) asymptotical…
Orthogonal Least Squares with Integrated Information Theoretic Criteria for Joint Number of Targets and DoA Estimation
Martin Willame, Gilles Monnoyer, François Horlin +1
We address the joint estimation of the number of targets and their direction-of-arrivals (DoAs) using antenna arrays. Target-number estimation can be formulated as a model-order se…
Near-Field Beampointing with Low Exposure Regions: a Dominant Subspace Projection Approach
Laurence Defraigne, Gilles Monnoyer, Jérôme Louveaux +1
The spherical nature of the wavefronts exhibited in the near-field of antenna arrays enables advanced beamforming capabilities, such as beampointing and beamnulling. In this paper,…
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…
