Abstract : The patent describes a new system and technique for providing multi-mode radar operation from a single scanning radar antenna at conventional scan rates. A single radar antenna has a plurality of feeds forming individual main-lobe beams equal in numer to the number of radar modes to be utilized. Each of the beams is separated in azimuth by a fixed angle theta and rotate together at the scan rate of the antenna. For each angle theta that the antenna rotates the radar mode is charged so that the antenna feeds are cyclically multiplexed to each of the radar modes desired.
