A two-dimensionally (2-D) scanning multibeam array with planar structure and low sidelobe level (SLL) is realized in this paper. It is for the first time that the SLL of 2-D scanning multibeam array ...

Direction-of-Arrival (DOA) estimation capability of sensor arrays is greatly influenced by geometric configuration of arrays. We proposed a new type 2-D planar array, improved Archimedean spiral array ...
