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. These set of sensors forms what is called a sensor array. Often there is the associated technique of beamforming which is estimating the signal from a given direction[1][2]. Various engineering problems addressed in the associated literature are:

Typical DOA estimation methods[edit]
