Abstract: An analog-to-digital converter circuit for a radar apparatus, the analog-to-digital converter circuit including analog-to-digital converters that are electronically reconfigurable to operate in a multi-channel mode with a first bandwidth by clocking the ADCs in phase with one another, or a single-channel mode with a second bandwidth higher than the first bandwidth by clocking the ADCs out of phase with one another and optimizing the intermediate frequency for the respective mode.

Abstract: Methods and apparatus for a radar system having an array including a series of concentric rings of array elements, wherein the concentric rings that have a shape defined by respective ellipses that increase in size from a center that is common to the respective ellipses. The series of concentric rings can include multiple groups of the concentric rings, wherein the concentric rings in each successive group are larger in size than the concentric rings in the first group.

Abstract: Methods and apparatus for an antenna having first and second nested monopoles each having arms with bends. In some embodiments, the monopoles are offset in clocking angle. In some embodiments, the monopoles are aligned in clocking angle. In embodiments, the bends in the arms may be located at half a total height of the antenna.
