Abstract
In one embodiment, an antenna device includes a scanning reflector, a fixed feeder interacting with the reflector for emitting radar radiation and a detector for detecting reflector passage of at least two different predetermined scanning positions during scanning of the reflector. The antenna device also includes a timer used to determine passage times at the time of reflector passage of the scanning positions. The scanning position of the reflector is predicted at an arbitrary time on the basis of the passage times and a predetermined scanning motion of the reflector. In another embodiment, a method for determining an accurate scanning position for the scanning reflector of the antenna device is disclosed.
