1. A RADAR antenna system comprising:
a base;
first and second antennas configured to transmit independent first and second antenna beams, respectively, the first and second antennas each being coupled to the base so as to provide a common rotational axis for the first and second antennas; and
an antenna position controller configured to independently control first and second transmission positions associated with the first and second antennas, respectively,
the antenna position controller and the first and second antennas cooperating to transmit the first and second antenna beams in different directions such that the first antenna beam is decoupled from the second antenna beam.
