A method for determining at least one object information item of at least one target object () which is sensed with a radar system (), in particular of a vehicle (), a radar system () and a driver assistance system () are described. In the method, transmission signals () are transmitted into a monitoring range () of the radar system () with at least one transmitter (). Echoes, which are reflected at the at least one target object (), of the transmission signals () are received as received signals () with at least one receiver (), and if necessary are converted into a form which can be used by an electronic control and/or evaluation device (). The received signals () are subjected to at least one multi-dimensional discrete Fourier transformation. At least one target signal is determined from the result of the at least one Fourier transformation. At least one object information item is determined from the at least one target signal. At the transmitter end, at least one first transmission signal () and at least one second transmission signal () are generated from a frequency-modulated continuous wave signal. The at least one second transmission signal () is encoded by means of phase modulation with respect to the at least one first transmission signal (), with the result that an at least temporary signal orthogonality between the at least one first transmission signal () and the at least one second transmission signal () is obtained. The at least one first transmission signal () is emitted with at least one first transmitter (), and the at least one second transmission signal () is emitted with at least one second transmitter (), simultaneously into the monitoring range () of the radar system (). The at least one second transmission signal () is emitted with regular transmission pauses of a predefined length.
