Abstract: In this paper, a comprehensive review is carried out of existing sparse arrays for direction-of-arrival (DOA) estimation of non-circular sources. We know that for DOA estimation of ...

Abstract: This paper presents an efficient optimization algorithm for synthesizing the discrete array factor, which extends the optimization domain to the invisible region to mitigate aliasing effect, ...

The evidence is solid but not definitive, as the conclusions rely on the absence of changes in spatial breadth and would benefit from clearer statistical justification and a more cautious ...
