DOI: 10.1109/lgrs.2025.3577369
Abstract: Multibeam frequency beam scanning leaky wave antennas (FBS-LWAs) enable a compact system with reduced bandwidth but introduce parasitic interference that impairs the direction-of-arrival (DOA) estimation. To solve this issue, this letter proposes a novel DOA… read more here.
