Abstract
In one embodiment, a method includes causing a radar antenna to transmit a plurality of radar signals at a plurality of sweep angles and, for each of one or more the radar signals reflected back to the radar antenna, calculating a radial-velocity component. The method also includes identifying one of the radial-velocity components, identifying one of the plurality of sweep angles corresponding to the identified radial-velocity components, and calculating an offset of an electrical boresight of the radar antenna based at least in part on the identified sweep angle corresponding to the identified radial-velocity component.
