A method for the suppression of interference radiation for a radar system for a motor vehicle, wherein - one or several sequences of identical high-frequency individual signals are radiated in a measuring cycle and the average time interval of said individual signals is greater than the propagation time of received signals that corresponds to a maximum distance of interest, particularly for determining the relative velocity of objects and for increasing the detection sensitivity, - received signals are mixed with high-frequency signals, whereby low-frequency receiving signals are generated that represent sequences of individual signals, characterized in that - the phase position thereof is varied over successive low-frequency individual receiving signals by varying the phase position i) of the individual transmitting signals or ii) or of the high-frequency signals used for mixing or iii) of the low-frequency individual receiving signals themselves, the method additionally comprises at least one of the following two features: - several antennas transmit simultaneously, wherein the phase position of the individual transmitting signals of different antennas relative to each other is varied, thereby allowing an at least approximate separation of the transmitting signals of different antennas when received by the same antenna, - several antennas receive simultaneously, wherein a summation of their receiving signals in the high-frequency or low-frequency range is performed and the phase position of the individual receiving signals of different antennas relative to each other is varied during said summation, thereby allowing an at least approximate subsequent separation of the receiving signals of different antennas in the signal processing means so that a part of the processing of the receiving signals can be performed in a shared path, wherein the variation of the phase position is used for making interference coupling or interference radiation caused by the radar system itself or by other systems behave in an uncorrelated manner relative to received signals of objects during signal processing so that a significant part of said coupling or radiation can be suppressed, said interference coupling or interference radiation occurring in the radar frequency range or in the range in which the low-frequency part of an electronic evaluation unit operates or is sensitive. - one or several sequences of identical high-frequency individual signals are radiated in a measuring cycle and the average time interval of said individual signals is greater than the propagation time of received signals that corresponds to a maximum distance of interest, particularly for determining the relative velocity of objects and for increasing the detection sensitivity, - received signals are mixed with high-frequency signals, whereby low-frequency receiving signals are generated that represent sequences of individual signals, - the phase position thereof is varied over successive low-frequency individual receiving signals by varying the phase position i) of the individual transmitting signals or ii) or of the high-frequency signals used for mixing or iii) of the low-frequency individual receiving signals themselves, the method additionally comprises at least one of the following two features: i) of the individual transmitting signals or ii) or of the high-frequency signals used for mixing or iii) of the low-frequency individual receiving signals themselves, - several antennas transmit simultaneously, wherein the phase position of the individual transmitting signals of different antennas relative to each other is varied, thereby allowing an at least approximate separation of the transmitting signals of different antennas when received by the same antenna, - several antennas receive simultaneously, wherein a summation of their receiving signals in the high-frequency or low-frequency range is performed and the phase position of the individual receiving signals of different antennas relative to each other is varied during said summation, thereby allowing an at least approximate subsequent separation of the receiving signals of different antennas in the signal processing means so that a part of the processing of the receiving signals can be performed in a shared path, wherein
