Patent ID: 7808427

Claim:
A radar system, comprising: a first transmit/receive module for a first frequency band and a first polarization; a second transmit/receive module for the first frequency band and a second polarization orthogonal to the first polarization; a third transmit/receive module for a second frequency band and the first polarization; a fourth transmit/receive module for the second frequency band and the second polarization orthogonal to the first polarization; a first plurality of splitter/combiners to receive outputs from the first and second transmit/receive modules; a second plurality of splitter/combiners to receive outputs from the third and fourth transmit/receive modules; a plurality of lens phase shifter pairs to receive outputs from the first plurality of splitter/combiners; a plurality of diplexers to receive signals from the plurality of lens phase shifter pairs and from the second plurality of splitter/combiners; and a radiator assembly including a series of radiator elements coupled to the plurality of diplexers.
