Abstract
Multiple-input multiple-output (MIMO) radar systems are equipped with channel extenders to further increase the number of receive and/or transmit antennas that can be supported by a given radar transceiver. One illustrative radar system includes: a radar transceiver to generate a transmit signal and to downconvert at least one receive signal; and a receive-side extender that couples to a set of multiple receive antennas to obtain a set of multiple input signals, that adjustably phase-shifts each of the multiple input signals to produce a set of phase-shifted signals, and that couples to the radar transceiver to provide the at least one receive signal, the at least one receive signal being a sum of the phase-shifted signals. An illustrative receive-side extender includes: multiple phase shifters each providing an adjustable phase shift to a respective input signal; a power combiner that forms a receive signal by combining outputs of the multiple phase shifters.
