Abstract: A RADAR antenna system and method are provided. In an implementation, the system includes a base and first and second antennas configured to transmit independent first and second antenna beams, respectively. The first and second antennas are each coupled to the base so as to provide a common rotational axis for the first and second antennas. An antenna position controller is configured to independently control first and second transmission positions associated with the first and second antennas, respectively. Two different antenna technologies can be used, for example one for providing communications capability and the other for providing tracking capability. Other implementations include four or more antennas configured to transmit beams at similar or different frequencies. Improvements in scan rate proportional to the number of antennas are achieved compared to that achievable with a single beam, without an increase in the rotation rate of the antenna system.

Abstract: A solid state RADAR antenna system is provided comprising at least one antenna configured to transmit a plurality of antenna beams. Each antenna beam is decoupled from each of the other plurality of antenna beams for transmitting in a blind range of a different antenna beam. Accordingly, in an implementation, the second antenna beam is transmitted so as to scan a first blind range associated with the first antenna beam. Decoupling antenna beams can be achieved using one or more of physical decoupling using different antennas, frequency decoupling using different bands and/or frequency multiplexing, or orthogonal polarization.
