Abstract
An inertial measurement unit (IMU) may be used to align a plurality of radar units coupled to a vehicle via a plurality of mounting structures. The IMU may be placed at a reference location and reference-location data may be captured. The IMU may be coupled to each of the mounting structures and, at each mounting structure, respective mounting-location inertial measurement data may be captured using the IMU. For each mounting structure, a measured roll angle, measured elevational angle, and measured azimuthal angle is determined based on at least the mounting-location inertial measurement obtained at the mounting structure and the reference inertial measurement. Further, for each mounting structure, offsets are determined for the measured roll angle, the measured elevational angle, and the measured azimuthal angle. One or more of the mounting structures and/or radar units are adjusted based on one or more of the offsets.
