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…

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…

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…
