In this paper, we propose a novel two-dimensional direction of arrival estimation technique for sparse arrays. To this end, we estimate the 2D difference coarray corresponding to the radar’s sparse ...

In this paper, a 3D beamforming phased array with 2D stacked tunable Nolen matrix is presented. The fundamental building block - tunable Nolen matrix is proposed to relax phase tuning range of phased ...
