A method for evaluating radar signals in a radar system including multiple sensor units, which are each capable of detecting objects in the surroundings of the radar system, the detection areas of the sensor units at least overlapping one another. In the method, each sensor unit calculates a short message from the radar signals received by it, whose data volume is smaller than the complete detection result, but which at least contains data which allow for the identification of potential objects and for the determination of a probability that the potential object is a real object, and at least one evaluation instance receives the entirety of all short messages of all sensor units and, on the basis of these short messages and selected detection results of the sensor units, calculates a consolidated detection result.

Method for evaluating radar signals in a radar system including multiple sensor units

An OFDM radar sensor including multiple transmission channels and at least one reception channel, and a method for operating such an OFDM radar sensor. At least for first transmission channels, the signal form of the signal to be transmitted, which includes a sequence of OFDM symbols in question, is progressively computed in portions for each transmission channel, and multiple buffer memories are used in alternation for storing a computed portion of the signal form and for reading out a previously computed and stored preceding portion of the signal form, which is converted from digital to analog and transmitted. A particular portion of the signal form is computed and stored in one of the buffer memories while a preceding portion of the signal form is being read out from another of the buffer memories and converted from digital to analog, and transmitted on the transmission channel in question.
