Multiple-beam phased array with switchable element areas

摘要

A phased array antenna system is provided, which includes one or more switchable sub-groups. Each switchable sub-group can be switchably configured to associate one or more waveform signals with one or more of a plurality of controller circuits using a first switching network, and to associate one or more of the plurality of controller circuits with one or more of a plurality of antenna elements using a second switching network. The switching networks permit a phased array antenna system to switchably control one or more beams, with different scanning ranges and coverage areas depending upon mission requirements.
