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 DOD and DOA?

Direction of departure (DOD) and direction of arrival (DOA) estimation [ P.

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.

What is DOA error?

The direction of arrival (DOA) estimation is a key measure of HF radar performance. Through both theoretical and experimental analysis, Lai et al. [6] found that the DOA error significantly depends on the ratio of the antenna pattern deviations of two loops for a cross-loop system.
