A method for reducing interference due to phase noise in a radar system, in which - in a first noncoherent transceiver unit (NKSE1), a first signal (sigTX1) is generated and transmitted, in particular emitted, via a path, - in a further, in particular second noncoherent transceiver unit (NKSE2), a first signal (sigTX2) is generated and transmitted, in particular emitted, via the path, - the first signals (sigTX1 and sigTX2) are received directly or indirectly in the respective other transceiver unit and are processed further therein as received signals (sigRX12 and sigRX21), - in the first transceiver unit (NKSE1), a comparison signal (sigC12) is formed from its first signal (sigTX1) and from such a first signal (sigRTX2) received from the further transceiver unit (NKSE2) via the path, and - in the further transceiver unit (NKSE2), a further comparison signal (sigC21) is formed from its first signal (sigTX2) and from such a first signal (sigTX1) received from the first transceiver unit (NKSE1) via the path, - wherein the further comparison signal (sigC21) is transmitted, in particular communicated, from the further transceiver unit (NKSE2) to the first transceiver unit (NKSE1), - wherein in a first step, deviations of the comparison signals (sigC21 and sigC12), which are induced by systematic deviations in the transceiver units (NKSE2, NKSE1), are compensated for, - wherein in a second step, at least one complex value from a first of the two comparison signals or from a signal which was derived from this first comparison signal is used to adapt at least one complex value of the second of the two comparison signals or a value of a signal which was derived from this second comparison signal, and thus to form an adapted signal (sigCC), - wherein the adaptation takes place such that by a mathematical operation, the vectorial sum or the difference of the complex values is formed. - in a first noncoherent transceiver unit (NKSE1), a first signal (sigTX1) is generated and transmitted, in particular emitted, via a path, - in a further, in particular second noncoherent transceiver unit (NKSE2), a first signal (sigTX2) is generated and transmitted, in particular emitted, via the path, - the first signals (sigTX1 and sigTX2) are received directly or indirectly in the respective other transceiver unit and are processed further therein as received signals (sigRX12 and sigRX21), - in the first transceiver unit (NKSE1), a comparison signal (sigC12) is formed from its first signal (sigTX1) and from such a first signal (sigRTX2) received from the further transceiver unit (NKSE2) via the path, and - in the further transceiver unit (NKSE2), a further comparison signal (sigC21) is formed from its first signal (sigTX2) and from such a first signal (sigTX1) received from the first transceiver unit (NKSE1) via the path, - wherein the further comparison signal (sigC21) is transmitted, in particular communicated, from the further transceiver unit (NKSE2) to the first transceiver unit (NKSE1), - wherein in a first step, deviations of the comparison signals (sigC21 and sigC12), which are induced by systematic deviations in the transceiver units (NKSE2, NKSE1), are compensated for, - wherein in a second step, at least one complex value from a first of the two comparison signals or from a signal which was derived from this first comparison signal is used to adapt at least one complex value of the second of the two comparison signals or a value of a signal which was derived from this second comparison signal, and thus to form an adapted signal (sigCC), - wherein the adaptation takes place such that by a mathematical operation, the vectorial sum or the difference of the complex values is formed.
