  • METHOD TO DETECT RADAR INSTALLATION ERROR FOR PITCH ANGLE ON AUTONOMOUS VEHICLES
    Publication number: 20230168363
    Abstract: A method may include receiving at least one camera frame of a first radar target and a second radar target, determining an estimated radar pose based at least in part on the at least one received camera frame, receiving a first radar cross-section (RCS) response from the first radar target and second radar target, determining an estimated elevation angle based at least in part on the first RCS response, and determining an estimated radar angle by refining the estimated radar pose and the estimated elevation angle based on at least in part on the first RCS response.
