Vehicle systems and cabin radar calibration methods

A method of assisting operation of a vehicle using a radar within an interior compartment of the vehicle, the method comprising:

• initiating, by a control module associated with the vehicle, operation of an interior component of the vehicle;
• receiving one or more reflected electromagnetic signals with the radar, wherein the operation of the interior component produces a Doppler shift in the one or more reflected electromagnetic signals;
• obtaining, by the control module, the one or more reflected electromagnetic signals from the radar within the interior compartment of the vehicle, wherein a frequency of the one or more reflected electromagnetic signals is influenced by the operation of the interior component;
• determining, by the control module, a measured position of the interior component based at least in part on the frequency of the one or more reflected electromagnetic signals;
• obtaining, by the control module, a reference position associated with the interior component;
• and
• determining, by the control module, a calibration offset for a reference axis associated with the radar based on a relationship between the measured position and the reference position and applying the calibration offset to modify at least one vehicle control function during subsequent operation.
