Abstract
A multi-chip MIMO radar system includes a plurality of transmitters and a plurality of receivers. Each of the pluralities of transmitters and receivers are arranged across a plurality of circuit chips. The multi-chip MIMO radar system includes a central processor configured to receive data from the plurality of circuit chips. The plurality of circuit chips generates sets of selected range, Doppler, and virtual receiver data. The central processor is operable to process the sets of selected range, Doppler, and virtual receiver data to produce selected range detection and angular resolvability of targets.
Claims19
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.
A multiple input, multiple output (MIMO) radar system comprising:
- a plurality of circuit chips, each configured as a separate system-on-chip radar system;
- wherein a first circuit chip of the plurality of circuit chips comprises a first plurality of transmitters and a first plurality of receivers arranged on the first circuit chip, wherein the transmitters and receivers of the first circuit chip are configured to produce a first set of selected range, Doppler, and virtual receiver data;
- wherein a second circuit chip of the plurality of circuit chips comprises a second plurality of transmitters and a second plurality of receivers arranged on the second circuit chip, wherein the transmitters and receivers of the second circuit chip are configured to produce a second set of selected range, Doppler, and virtual receiver data;
- and
- a processor configured to receive the first and/or second set of selected range, Doppler, and virtual receiver data from the respective first circuit chip and/or second circuit chip, wherein the processor is further configured to perform target detection and angle estimation;
- 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 the first and second circuit chips are configured to perform respective selected target detection and angle estimation to produce the first and second sets of selected range, Doppler, and virtual receiver data, and wherein the selected target detection and angle estimation of the first and second circuit chips comprises a lower range detection and/or angular resolution performance as compared to the target detection and angle estimation of the processor.
