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.
