Near-Field Localization and Sensing With Large-Aperture Arrays: From signal modeling to processing

The signal processing community is currently witnessing a growing interest in near-field signal processing, driven by the trend toward the use of large-aperture arrays with high spatial resolution in the fields of communication, localization, sensing, imaging, and so on. From the perspective of localization and sensing, this trend breaks the basic far-field assumptions that have dominated the array signal processing research in the past, presenting new challenges and promising opportunities.
