The invention relates to a method for evaluating a radar signal in a radar system (10) having a plurality of sensor units (12), each of which can detect an object in the surroundings of the radar system, the detection regions of the sensor units (12) at least overlapping one another, characterized in that the radar signal is evaluated in the radar system (10). Each sensor unit (12) calculates a short message (16) from the radar signal received by the sensor unit, the amount of the short message being smaller than the complete detection result, but the short message containing at least the following data: the data allows a potential object to be recognized and determines the probability that the potential object relates to a real object; at least one evaluation device (14) receives all short messages (16) of all sensor units (12) and calculates a combined detection result on the basis of the short messages and selected detection results of the sensor units (12). The invention also relates to a corresponding ra
