Abstract
A mechanism is provided for estimating mounting orientation yaw and pitch of a radar sensor without need of prior knowledge or information from any other sensor on an automobile. Embodiments estimate the sensor heading (e.g., azimuth) due to movement of the automobile from radial relative velocities and azimuths of radar target detections. This can be performed at every system cycle, when a new radar detection occurs. Embodiments then can estimate the sensor mounting orientation (e.g., yaw) from multiple sensor heading estimations. For further accuracy, embodiments can also take into account target elevation measurements to either more accurately determine sensor azimuth and yaw or to also determine mounting pitch orientation.
