Abstract
A radar system, such as a weather radar system, includes a radar antenna and a processor. The processor is configured to cause a first radar beam to be provided using a first portion of the radar antenna. The processor is configured to cause a second radar beam to be provided using a phase adjusted portion of the antenna and a remaining portion of the radar antenna. A radar method and system can allow multiple low-loss overlapping radar beams to be rapidly generated to support a sequential lobbing process which may be used to generate intra-beam target angle estimates. The production of these overlapping beams does not require mechanical antenna movement but beam selection is controlled by a simple electronic switch in some embodiments.
