More than two decades have passed since geologists first identified an unusual circular structure buried beneath the North Sea, and now scientists say new evidence could finally solve the mystery. New ...

Abstract: Estimating angles for coherent signals remains a critical challenge in array signal processing. Traditional spatial smoothing techniques can recover the rank loss caused by signal coherence, ...

Abstract: This paper proposes an interference suppression beamforming method for sparse circular arrays (SCAs) based on the joint updated diagonal loading (UDL) and combined particle swarm ...
