For detection of an electromagnetic signal, which is transmitted from a transmitting antenna (2), by means of at least two at least essentially identical receiving antennas (3, 4), whose sensitivity curve has a maximum (M) with falling flanks as well as sidelobes (SL) adjacent to it with sensitivity increased again at a reception angle symmetrically with respect to a basic alignment, with angle determination for an object which reflects the transmitted signal being carried out by the two receiving antennas (3, 4) by phase determination in an unambiguity area (.theta.u) whose boundaries (L) are predetermined by the distance (d) between the receiving antennas (3, 4), the distance (d) is chosen such that the boundaries (L) of the unambiguity area (.theta.u) intersect the sidelobes (SL), and the reflective object is detected by means of vectorial addition of the signals from the receiving antennas (3, 4), after which the parameters R, v are determined.
