Abstract

Example embodiments relate to real-time health monitoring for automotive radars. A computing device may receive radar data from multiple radar units that have partially overlapping fields of view and detect a target object located such that the radar units both capture measurements of the target object. The computing device may determine a power level representing the target object for radar data from each radar unit, adjust these power levels, and determine a power difference between them. When the power difference exceeds a threshold power difference, the computing device may perform a calibration process to decrease the power difference below the threshold power difference or alert the vehicle, including onboard algorithms, to the reduced performance of the radar.
