Patent ID: 11965976
Assignee: INFINEON TECHNOLOGIES AG
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G

Claim 15:
16. A system comprising:
radar hardware comprising
RF circuitry configured to be coupled to a receive antenna and a transmit antenna,
a frequency generation circuit coupled to the RF circuitry, and
an analog-to-digital converter coupled to the RF circuitry;

a data communication interface configured to be coupled to an external host; and
a radar controller coupled to the radar hardware and to the data communication interface, the radar controller comprising a processor configured to implement the following functions:
a communication protocol configured to interact with the external host via the data communication interface,
an antenna controller configured to interact with the RF circuitry, and
a chirp generator configured to interact with the frequency generation circuit, wherein the radar controller is configured to
receive radar configuration data comprising chirp parameters from a host via the data communication interface,
upon receipt of the radar configuration data, configure the frequency generation circuit with the radar configuration data,
receive a trigger command from the host via the data communication interface; and
upon receipt of the trigger command,
trigger the frequency generation circuit to perform a frequency ramp based on the radar configuration data,
receive samples from the analog-to-digital converter of the radar hardware, and
send the received samples to the host via the communication protocol.
