FIELD: physics.
SUBSTANCE: method is realised by enabling separation of an echo signal on several beams, measuring angle of arrival values of the echo signal on separate beams, as well as enabling operation of the device for measuring angle of arrival of the echo signal on beams in different noise conditions in processing channels corresponding to different fan directional characteristics.
EFFECT: high accuracy of determining the angle arrival of an echo signal.
