摘要：The device for receiving signals which have carrier frequencies and codes, saidsignals being navigation or communication signals, has multiple individual antennas () forreceiving a signal, each individual antenna () having an antenna output () at which the

received signal is present. Furthermore, the device is provided with an analog

preprocessing unit () for preprocessing the signals received by the individual antennas (),said preprocessing unit () having signal transmitting and signal preprocessing channels ()which are assigned to the individual antennas (), and the device is provided with a digitalsignal processor (). The device additionally has a calibration signal generating unit () forgenerating a calibration signal which, like the signals received by the individual antennas(), has a carrier frequency and a code and which is used for calibrating the propagationtime and the phase of the signal transmission paths. Additionally, a reference frequencygenerating unit () is also provided that generates a reference frequency with which theanalog preprocessing unit (), the digital signal processor (), and/or the calibration signalgenerating unit () can be operated and/or on the basis of which other operatingfrequencies with a specifiable relationship to the reference frequency can be generatedin order to operate the analog preprocessing unit (), the digital signal processor (),and/or the calibration signal generating unit ().
