    摘要: A method and an apparatus for operating a radar sensor system with a number of adjacent individual sensors (3, 4, 5, 6), extensively synchronized with one another, for determining the position of a target object (15) are proposed. In one measurement cycle, the transit time of the radar signal emitted from one individual sensor and reflected by the target object to this individual sensor (3, 4, 5, 6) (direct echo (13, 14)) and to a different individual sensor (3, 4, 5, 6) (cross echo (16)) is evaluated. From the evaluation of the direct and cross echoes (13, 14, 16), at least the position of the target object (15) is determined, and a detection quality signal (Q) is ascertained, and once a predetermined amount of the detection quality signal (Q) is reached for a target object (15), a calibration is performed.
