Abstract
In accordance with an embodiment, a method of operating a radar system includes receiving radar configuration data from a host, and receiving a start command from the host after receiving the radar configuration data. The radar configuration data includes chirp parameters and frame sequence settings. After receiving the start command, configuring a frequency generation circuit is configured with the chirp parameters and radar frames are triggered at a preselected rate.
Claims20
A method of operating a radar system, the method comprising:
- receiving radar configuration data from a host, the radar configuration data comprising chirp parameters;
- upon receipt of the radar configuration data, configuring a frequency generation circuit with the chirp parameters;
- receiving a trigger command from the host;
- and
- upon receipt of the trigger command, triggering the frequency generation circuit to perform a frequency ramp based on the chirp parameters, receiving samples from the radar system, and sending the received samples to the host.
A radar system comprising:
- a processor circuit configured to be coupled to radar hardware;
- and
- a non-transitory computer readable medium coupled to the processor circuit, the non-transitory computer readable medium comprising an executable program thereon, wherein the executable program instructs the processor circuit to perform the steps of:
- receiving radar configuration data from a host, the radar configuration data comprising chirp parameters;
- upon receipt of the radar configuration data, configuring a frequency generation circuit with the chirp parameters;
- receiving a trigger command from the host;
- and
- upon receipt of the trigger command, triggering the frequency generation circuit to perform a frequency ramp based on the chirp parameters, receiving samples from the radar system, and sending the received samples to the host.
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;
- and
- a radar controller coupled to the radar hardware, the radar controller comprising a processor configured to implement the following functions:
- a communication protocol configured to interact with an external host,
- an antenna controller configured to interact with the RF circuitry, and
- a chirp generator configured to interact with the frequency generation circuit.
