Abstract: This letter introduces Adaptive Nyström Spectral Analysis (ANSA) as a new technique for Direction of Arrival (DOA) estimation in coprime arrays. ANSA exploits Nyström-based root-MUSIC, ...
Abstract: A Cramér-Rao bound (CRB) optimization framework for near-field sensing (NISE) with continuous-aperture arrays (CAPAs) is proposed. In contrast to conventional spatially discrete arrays ...
