1. A radar method for exchanging signals between at least two non-coherent transceiver units, the method comprising:
aligning clock offsets and/or clock rates of respective clock sources of the at least two transceiver units;
performing a full-duplex measuring process, in which a first transmit signal is transmitted from a first transceiver unit to a second transceiver unit and a second transmit signal is transmitted from the second transceiver unit to the first transceiver unit, the measuring process comprising generating a comparison signal in each of the first transceiver unit and the second transceiver unit by mixing and/or correlating the first transmit signal with a received second transmit signal and vice versa, respectively; and
exchanging the comparison signals between the transceiver units as part of the full-duplex measuring process:
wherein the alignment of clock offsets and/or clock rates is performed 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.
