ABSTRACT:
A two-dimensional (2D) radar antenna system includes a combination of power divider networks coupled together to drive an array of antenna elements to form two beams in different directions spatially. The power divider networks, in combination, have characteristics which effect power concentrations of the two formed beams at different locations in the array without significant loss of illuminating power. As a result, the two formed beams render both amplitude and phase angle difference signals with respect to a common detected target which may be used to accurately and uniquely measure the elevation of the target.
