Abstract
A new system and technique for providing multi-mode radar operation from a ingle scanning radar antenna at conventional scan rates. A single radar antenna has a plurality of feeds forming individual main-lobe beams equal in number 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 changed so that the antenna feeds are cyclically multiplexed to each of the radar modes desired.
