By piggybacking a millimeter wave radar onto an X-band instrumentation radar, the Navy has come up with an accurate method of tracking targets close to the horizon. Usually at low-elevation angles, error is introduced by a portion of the echo signal being reflected from the ocean or the earth's surface, which cane nter the main lobe or close-by sidelobes. As elevation angles become less than two beamwidths, the multipath errors become significant and eventually so large that the radar loses track.
