Presented is a method for determining speeds (vr14, vr16) and distances (r14, r16) of objects (14, 16) relative to a radar system (12) of a motor vehicle (10), wherein a coverage area (EB) of the radar system (12) is divided into at least two part-areas (TB1, TB2, TB3), the coverage area (EB) is examined for reflecting objects (14, 16) in successive measuring cycles (MZ1, MZ2; MZi, MZi+1), wherein radar signals received in a measuring cycle (MZ1, MZ2; MZi, MZi+1) are processed separated in accordance with part-areas (TB1, TB2, TB3) and processed signals are assembled to form a total result differentiated in accordance with spatial directions. The method is characterized in that from signals received in a first measuring cycle (MZ1; MZi), hypotheses for the distance (r14, r16) and speed (vr14, vr16) of reflecting objects (14, 16) are formed and the hypotheses are validated in dependence on signals received in at least one further measuring cycle (MZ2; MZi+2). Furthermore, a radar system (12) is presented which carries out such a method. |
