Abstract: Large-scale uniform arrays encounter critical challenges due to dense element arrangements, including excessive hardware, elevated computational complexity, high costs, strong mutual ...

Abstract: Sparse arrays enable high performance with fewer sensors but pose a challenging combinatorial design problem, especially for wideband beamforming. In this paper, a dual-head wideband sparse ...

Uses a shallow tree structure with a branching factor of 4096 to index a series of small arrays that try to compress as much as possible to reduce the memory overhead needed. Similar to a Map, except ...
