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 ...

This paper is focus on describe a new methodology for the 2D (Azimuth and Elevation) estimation of the direction of arrival (DOA) of quasi-stationary signals, based on a Khatri-Rao (KR) subspace ...
