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 music DOA?

DOA is for the direction of array antenna of the radio wave. If the radio wave received meets the condition of far field narrowband, it can take the front of the radio wave as a plane. The angle between the array normal and the direction vector of the plane wave is the Direction of arrival (DOA).

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.

Why is music super resolution?

MUltiple SIgnal Classification (MUSIC) is a high-resolution direction-finding algorithm based on the eigenvalue decomposition of the sensor covariance matrix observed at an array. MUSIC belongs to the family of subspace-based direction-finding algorithms.
