Abstract
The present invention relates to a method for determining a direction to a signal-emitting object by means of a platform comprising at least two antennas separated by a known distance. The method comprises said steps of: receiving, with each of said at least two antennas, a signal from said signal-emitting object at first positions, determining a first phase relation of said signal between said at least two antennas, —receiving, with each of said at least two antennas, a signal from said signal-emitting object at at least second positions, determining at least a second phase relation of said signal between said at least two antennas, characterized by the steps of: determining change(s) in position(s) of at least one antenna of said at least two antennas, and determining a direction to a signal-emitting object based on said first phase relation, said at least second phase relation and said change(s) in position(s) of said at least one antenna. The invention further relates to a platform performing a determination of a direction to a signal-emitting object.
