A radar test system that identifies MIMO radar transmit antenna reconfiguration sequences by quantizing temporal power level profiles and matching them against a stored record.

Patentradars sammanfattning

The disclosed radar test system addresses the challenge of testing MIMO automotive radar systems by automatically detecting which transmit antenna reconfiguration sequence a radar under test (RUT) is currently employing. The system uses one or more power detectors to derive a temporal power level profile of received radar signals, quantizes that profile into K discrete power levels, and compares it against a pre-built record of known transmit antenna reconfiguration sequences and their associated activity patterns. Once a match is found, all relevant modulation parameters are read directly from the record rather than estimated from the received signal, guaranteeing accuracy and enabling the radar target simulator to correctly emulate target angles and adapt to future antenna configuration changes.
