Method and device for non-coherent distributed full-duplex transmission radar systems

A radar system for determining a distance and/or a relative speed, the system comprising:

• at least two non-coherent transceiver units, that respectively have non-synchronous clock sources;
• a synchronization device for aligning clock offsets and/or clock rates of the clock sources of the at least two transceiver units;
• wherein the transceiver units are configured to perform a full-duplex measuring process, in which a first transmit signal of a first transceiver unit is transmitted to a second transceiver unit and a second transmit signal of the second transceiver unit is transmitted to the first transceiver unit;
• wherein the synchronization device is configured to perform the alignment of clock offsets and/or clock rates prior to the full-duplex measuring process, such that a time offset and/or a frequency offset between the transmit signals remains at least substantially constant during a transmission time of the full-duplex measuring process;
• wherein the first transceiver unit is configured to generate a comparison signal by mixing and/or correlating the first transmit signal with a received second transmit signal and the second transceiver unit is configured to generate another comparison signal by mixing and/or correlating the second transmit signal with a received first transmit signal, and
• wherein the transceiver units are further configured to exchange the comparison signals as part of the full-duplex measuring process.
