What is DOA algorithm?

Direction-of-arrival (DOA) estimation refers to the process of retrieving the direction information of several electromagnetic waves/sources from the outputs of a number of receiving antennas that form a sensor array.

What is the music algorithm?

The basic idea of MUSIC algorithm is to conduct characteristic decomposition for the covariance matrix of any array output data, resulting in a signal subspace orthogonal with a noise subspace corresponding to the signal components.

What is root music algorithm?

The multiple signal classification (MUSIC) algorithm used by rootmusic is the same as that used by pmusic . The algorithm performs eigenspace analysis of the signal's correlation matrix in order to estimate the signal's frequency content.

What is DOA in radar?

In signal processing, direction of arrival (DOA) denotes the direction from which usually a propagating wave arrives at a point, where usually a set of sensors are located.
