Abstract

The embodiments relate to signal selection devices for reception antennas. The signal selection device includes a plurality of signal inputs for the reception of signals from the reception antennas via an interface arrangement, and a plurality of signal outputs for the output of altered signals from the reception antennas. The signal selection device is used for selecting/reducing received signals from the reception antennas and forwarding them to an image processing device. The signal selection device contains a plurality of A/D converter chips, a plurality of digital selection chips, and at least physical and/or logical portions of a control unit. The received signals from the reception antennas are fed into the plurality of A/D converter chips via a plurality of signal inputs, are converted into digital data streams, and are supplied to the digital selection chips via signal outputs of the A/D converter chips.
