Abstract

A method is described in particular 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 (SP), in a further, in particular second noncoherent transceiver unit (NKSE2), a first signal (sigTX2) is generated and transmitted, in particular emitted, via the path (SP), the 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 (SP), 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 (SP), wherein the further comparison signal (sigC21) is transmitted, in particular communicated, from the further transceiver unit (NKSE2) to the first tra…
