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 ...

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 ...
