Abstract
The invention describes a method for reducing interference effects in a radar system, which has at least two transceiver units (S, S), which are in particular spatially separated from one another, wherein the method comprises the following steps: —a transmission step (VS), in which a first transmission signal (sigTX) of the first transceiver unit (S) is sent and received to and by a second transceiver unit (S) and a second transmission signal (sigTX) of the second transceiver unit (S) is sent and received to and by the first transceiver unit (S) via a radio channel (T), wherein the transmission signals (sigTX, sigTX) are modulated according to an orthogonal frequency multiplex method; and—a pre-correction step (VS), in which correction values (γ1, γn, γ2) are determined from the received transmission signals (sigTX, sigTX) and in particular are exchanged between the transceiver stations (S, S), wherein the received transmission signals (sigRX, sigRX) are postprocessed on the basis of the correction values (γ1, γn, γ2), so that influences of interference variables, in particular of phase noise and/or a time offset and/or unknown initial phase positions, are reduced.
