Abstract

In order to efficiently estimate the angle of arrival (AOA) information from the closely located signal sources, in this paper, we introduce a cascade AOA estimation technique based on the CAPON and beamspace Multiple Signal Classification (MUSIC) algorithms. First, the cascade approach estimates AOA groups consisting of multiple AOAs using CAPON, and then estimates the individual AOA in the AOA group using beamspace MUSIC. In this paper, we employ the rectangular array anttena for the cascade algorithm.
