A method and an apparatus for aligning the elevation of an automotive radar unit. The method of aligning a radar transceiver unit ( ) on a vehicle ( ) having the steps of: positioning at least three radar reflectors ( ) in a pattern in which the reflectors are fixed relative to one another with the reflectors occupying three rows ( ) at different elevations and at least three different horizontal positions ( ), so that the middle row ( ) is horizontally distinguishable from the neighboring rows ( ); directing a beam (14) of radar waves ( ) from the radar transceiver ( ) generally towards the radar reflectors ( ); scanning ( ), and if necessary repeatedly scanning, the beam (14) relative to the pattern so that the beam moves across the pattern at one or more fixed elevations in a horizontal direction; receiving at the radar transceiver ( ) radar waves reflected ( ) from one or more of the reflectors ( ); detecting the elevation of the middle row ( ); setting the elevation of the beam ( ) of radar waves according to the detected elevation of the middle row ( ).
