1. A system for object detection, comprising:
a first one-dimensional radar array including a plurality of first antenna elements that are arranged corresponding to a first axis along an azimuthal plane and configured to transmit first signals and receive first reflections based at least in part on the first signals;
a second one-dimensional radar array including a plurality of second antenna elements that are arranged corresponding to a second axis along an elevation plane and configured to transmit second signals and receive second reflections based at least in part on the second signals; and
at least one processor configured to detect an object based at least in part on first information output from the first one-dimensional radar array and to determine an elevation associated with the object based at least in part on:
second information output from the second one-dimensional radar array, and
the object being within a range associated with the second one-dimensional radar array.
