1. A multiple input, multiple output (MIMO) radar system comprising:
a first plurality of transmitters and a first plurality of receivers arranged on a first circuit chip, wherein the transmitters and receivers of the first circuit chip are configured to perform selected range, Doppler, and virtual receiver processing on a first set of data, and wherein the transmitters and receivers of the first circuit chip are configured to select a first subset of data from the first set of data; and
a second plurality of transmitters and a second plurality of receivers arranged on a second circuit chip, wherein the transmitters and receivers of the second circuit chip are configured to perform selected range, Doppler, and virtual receiver processing on a second set of data, and wherein the transmitters and receivers of the first circuit chip are configured to select a second subset of data from the second set of data;
wherein the first circuit chip is configured to perform the selected range, Doppler, and virtual receiver processing independent of the second circuit chip; and
wherein a processor is configured to receive the first and second subsets of data and perform target detection and angle estimation using the first and second subsets of data, and wherein the resulting target detection and angle estimation produced by the processor comprises a higher range detection and/or angular resolution performance as compared to any respective target detection and angle estimation performed by the transmitters and receivers of the respective first and second circuit chips.
