Zusammenfassung:	A method and apparatus for processing electromagnetic waves. Electromagnetic waves are transmitted in a selected direction toward a target object from a first array of antenna elements. Scattered electromagnetic waves generated from the electromagnetic waves are received at a first portion of a second array of antenna elements configured to receive the scattered electromagnetic waves in a first direction with respect to the selected direction and at a second portion of the second array of antenna elements configured to receive the scattered electromagnetic waves in a second direction with respect to the selected direction. First information in the scattered electromagnetic waves received by the first portion is subtracted from second information in the scattered electromagnetic waves received by the second portion to form difference data. An elevation angle is identified between a direction of the target object and the selected direction using the difference data.
