Assignee: NXP B.V.
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. An apparatus comprising:
a radar circuit to receive reflection signals, in response to transmitted chirp sequences, as reflections from objects remote from the apparatus;
computer processing circuitry to process data corresponding to the reflection signals and, in response, to generate output data indicative of distance, velocity and/or angle information; and
emulation circuitry to introduce one or more sets of diagnostic data into the radar circuit to cause circuit processing of simulated reflection signals as though the simulated reflection signals are reflections from the objects remote from the apparatus, each of the one or more sets of diagnostic data being respectively associated with one or more simulated targets and including a first effective signal delay to create the simulated reflection signals,
wherein each of the one or more sets of diagnostic data further includes a second effective signal delay between the chirp sequences to introduce a phase offset, and wherein the emulation circuitry and/or the radar circuit are to use transmit phase rotator to position the first effective signal delay and the second effective signal delay.
