    摘要: A method and device for synchronizing a transmitter and a receiver with each other over a radio interface. A transmission signal is produced with a signal source in the transmitter and is transmitted via the radio interface. A corresponding receiver signal is received in the receiver from the radio interface and is evaluated using a receiver signal source signal from a signal source of the receiver adapted to the signal source of the transmitter. The same frequency modulation is applied to the receiver signal source signal, whereby the receiver signal received in the receiver is mixed with the receiver signal source signal to form a mixed signal and the mixed signal is analyzed with respect to frequency unbalance.

    摘要: A multistatic detection device for measuring a distance to an object includes a transmitter and a receiver, each having a high-frequency oscillator and a pulse generator. The pulse generators can be supplied with synchronisation signals emitted by signals generators, the synchronisation signals being transmitted by a data bus common to the transmitter and the receiver. The relation of the deterministic phases of high-frequency signals can be produced by the high-frequency oscillator. The method includes feeding two synchronisation signals to the transmitter and the receiver by the common data bus, the transmitter signal is transmitted towards an object, the signal passing through the receiver and contained in the data bus being mixed with a reception signal reflected by the object, thereby producing a measuring signal thereby making it possible to compare the phases of clock signals.

    摘要: The invention relates to a device, especially an active backscatter transponder, for generating an oscillator signal based on a base signal. It comprises an oscillator for actively constructing the oscillator signal by oscillations, an input for the base signal and an output for the oscillator signal produced. The oscillator can be induced by the base signal to generate oscillator signal in a quasi-coherent manner to the base signal. For the transmission of data, the device further has a data insertion device for inserting data or a data signal into the oscillator signal. A corresponding suitable receiver receives and processes the received signal that was generated and transmitted by such a device as a quasi-coherent signal. A separation device removes the signal portions of the oscillator from the received signal via the base signal of a receiver-side oscillator, with a data retrieval device for retrieving the inserted data.
