Claim 0:
1. A radar system comprising:
an antenna configured to receive electromagnetic (EM) energy reflected by one or more objects, the antenna comprising:
a first one-dimensional (1D) subarray comprising a first quantity of antenna elements;
a second 1D subarray positioned orthogonal to the first 1D subarray and comprising a second quantity of antenna elements; and
a two-dimensional (2D) subarray comprising a third quantity of antenna elements that is less than a product of the first quantity and the second quantity; and

one or more processors configured to:
determine, using the EM energy received by the first and second 1D subarrays, first angles and second angles, respectively, associated with the one or more objects; and
determine relative locations of the one or more objects by associating, using the EM energy received by the 2D subarray, respective first angles of the first angles to respective second angles of the second angles.
