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.

A radar system, comprising:
- a radar array including a series of concentric rings of array elements, wherein the concentric rings have a shape defined by respective ellipses, wherein the concentric rings increase in size from a center that is common to the respective ellipses, the series of concentric rings including:
- a first group of the concentric rings, wherein a subset of the array elements comprising one out of every four array elements in the first group is configured for multi-band;
- and
- a second group of the concentric rings, wherein the concentric rings in the second group are larger in size than the concentric rings in the first group.
