The reflector antenna also as a plurality of antenna elements arranged side by side and in a row, for transmitting radar transmission signals and receiving radar reception signals produced from a reflection on a surface. The reflector is designed as a one-dimensional defocused reflector having two focal planes. The optical axis coincides with the line of inter-section of two imaginary planes extending at right angles to one another. The reflector has, in a first (X-) plane, a first (X-) focal plane that extends at right angles thereto and to the optical axis, and, in a second (Y-) plane, a second (Y-) focal plane which extends at right angles thereto and to the optical axis. The second (Y-) focal plane is at a greater distance from the vertex than the first (X-) focal plane.

  • Patent number: 9352517
    Abstract: This application describes a tool, an arrangement, and a method of manufacturing a component. The manufacturing of the component is achieved by a resin transfer from a storage chamber via a transfer line into a working chamber. Before the resin transfer, taking place, for example by a compressed air charging of the storage chamber, the storage chamber is filled with an amount of resin adjusted to the size of the component. Furthermore, a semi-finished product, consisting of cut-to-size reinforcement fibers, is inserted into the working chamber that is adjusted to the form of the component to be produced. Storage chamber, transfer line, and working chamber are configured in a one-piece mould casing of the tool. The application further describes a component manufactured by the above-mentioned tool or by the above-mentioned method respectively.
