Direction of Arrival Estimaation Analysis Using a 2D Antenna Array

The direction of arrival of the incoming signals to an antenna array is one of the properties which can be obtained through the processing of the received data. This property is an important key in the development of adaptive antennas, enabling to discover the number of impinging signals to an antenna and its directions. This paper describes the most known algorithms that determine the directions of arrival using a two dimensional antenna array, analyzing its performance. Properties such as the computational efficiency and estimation accuracy using several scenarios of noise are presented.
