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).
