Abstract
A radar system uses a rotating antenna array having rows that display dispersive properties while feeding multiple radiating elements. In some embodiments, the radiating elements are dual polarized. In at least one embodiment, beam spoiling may be used to generate an unfocused transmit beam that covers an entire elevation range of interest. Digital beam forming may be used during a receive mode to achieve a stack of narrow-width receive beams in elevation. Frequency scanning may also be used to achieve stacked beams in azimuth.
