Abstract: In this paper, the problem of joint time-of-arrival and two-dimensional direction-of-arrival (TOA/2D-DOA) estimation is solved using space-frequency nested array (SFNA) motion. SFNA is ...

Abstract: Two-dimensional direction-of-arrival (2D-DOA) estimation plays a key role in array signal processing by providing accurate azimuth and elevation information. This full spatial awareness is ...
