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 (NKSE) a first signal (sigTX) is generated and transmitted, in particular emitted, via a path (SP), in a further, in particular second noncoherent transceiver unit (NKSE), a first signal (sigTX) is generated and transmitted, in particular emitted, via the path (SP), the signals (sigTXand sigTX) are received directly or indirectly in the respective other transceiver unit and are processed further therein as received signals sigRXand sigRX, in the first transceiver unit (NKSE), a comparison signal (sigC) is formed from its first signal (sigTX) and from such a first signal (sigRTX) received from the further transceiver unit (NKSE) via the path (SP), and in the further transceiver unit (NKSE), a further comparison signal (sigC) is formed from its first signal (sigTX) and from such a first signal (sigTX) received from the first transceiver unit (NKSE) via the path (SP), wherein the further comparison signal (sigC) is transmitted, in particular communicated, from the further transceiver unit (NKSE) to the first transceiver unit (NKSE), wherein in a first step, deviations of the signals sigCand sigCwhich are induced by systematic deviations in the transceiver units (NKSE, NKSE), 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 for the purpose of adapting at least one complex value of the second of the two comparison signals or a value of a signal which was derived from the second comparison signal, and thus to form a signal (sigCC), wherein the adaptation takes place such that by a mathematical operation, the vector sum or the difference of the complex values is formed or the sum or the difference of the phases of the complex values is formed.
