Abstrakt

A plant for generation of information indicative of the depth and the orientation of an object positioned below the surface of the ground is adapted to use electromagnetic radiation emitted from and received by an antenna system associated with the plant. The plant has a transmitter and a receiver for generation of the electromagnetic radiation in cooperation with the antenna system mentioned and for reception of the electromagnetic radiation reflected by the object in cooperation with the antenna system, respectively. The antenna system includes a plurality of individual antenna elements such as dipole antennas, having substantially linear polarization. The antenna elements are positioned in relation to the geometric center of the antenna system, with the various centers of the antenna element displaced in relation to the geometric center of the antenna system. The plant has a mechanism for rotating the antenna system and thus polarizing the electromagnetic field around or in relation to the geometric center of the antenna system.
