Abstract
A radar system for use in a vehicle moving in a first direction may include a plurality of antenna elements spaced apart in a second direction; and a controller operably connected to the plurality of antenna elements. The controller may be configured record signals received by each antenna element at each time instant of a plurality of time instants; calculate a position in the first direction of each antenna element for each time instant based on a velocity hypothesis; calculate a virtual two-dimensional antenna array response based on the signal received by each antenna element at each time instant and the position in the first direction of each antenna element at each time instant; calculate a beamforming spectrum based on the virtual two-dimensional antenna array response; and identify a peak in the beamforming spectrum to identify an elevation angle from the vehicle to a target relative to the first direction.
