Systems and methods for blind online calibration of radar systems on a vehicle

A system comprising:

• one or more non-transitory computer-readable storage media embodying instructions;
• and
• one or more processors coupled to the storage media and operable to execute the instructions to:
• transmit, from a processor to the sensor unit, a control signal that causes the sensor unit installed with the vehicle to be tuned to a plurality of positions while the vehicle is in motion;
• obtain a plurality of sensor data scans captured by the sensor unit while the sensor unit is tuned to the plurality of positions;
• identify one or more target points from each of the plurality of sensor data scans, wherein the one or more target points represent one or more static objects in an environment that the vehicle is situated at while in motion;
• and
• determine a calibration position for the sensor unit based on a trajectory pattern of the one or more target points over the plurality of sensor data scans.

One or more non-transitory computer-readable storage media embodying software that is operable when executed by a computing system to:

• transmit, from a processor to the sensor unit, a control signal that causes the sensor unit installed with the vehicle to be tuned to a plurality of positions while the vehicle is in motion;
• obtain a plurality of sensor data scans captured by the sensor unit while the sensor unit is tuned to the plurality of positions;
• identify one or more target points from each of the plurality of sensor data scans, wherein the one or more target points represent one or more static objects at a location that the vehicle is at while in motion;
• and
• determine a calibration position for the sensor unit based on a trajectory pattern of the one or more target points over the plurality of sensor data scans.
