A system for generating a pseudomonopulse tracking error includes an antenna system ( 401 ) that generates a sum antenna beam and a difference antenna beam. The sum antenna beam has a pattern with a peak gain on the boresight axis, and the difference antenna beam has a pattern that is circularly symmetric and forms a null about the boresight axis. The difference antenna beam has a relative phase that varies 360 degrees around the boresight axis. A differential phase dispersion is provided as between the sum and difference RF channels ( 405, 407 ) to providing a rotating scanning plane ( 702 ).
