Abstract

An apparatus for determining information on a position of a transmitter. In one example, the apparatus includes an antenna apparatus, a control apparatus and a data processing apparatus. The antenna apparatus includes several different directional characteristics, wherein the directional characteristics are each related to an amount of spatially different receive sensitivities of the antenna apparatus. The control apparatus influences the antenna apparatus such that at least one of the directional characteristics of the antenna apparatus is activated. With the activated directional characteristic, the antenna apparatus receives a signal originating from the transmitter. The data processing apparatus processes the received signal and the amount of spatially different receive sensitivities allocated to the related activated directional characteristic to an amount of weighted receive values and determines the information on the position of the transmitter therefrom. Further, the invention relates to a respective method.
