interferometry
The use of interference phenomena for purposes of measurement.
In radar, one use of interferometric techniques is to determine the angle of arrival of a wave by comparing the phases of the signals received at separate antennas or at separate points on the same antenna. Another interferometric application is to shape and steer the beams of phased- array antennas by adjusting the phases of the different elements of the array.
