Abstract (en)
[origin: WO2017097493A1] The invention relates to a radar sensor device (15) for a driver assistance system (14) of a motor vehicle (13) for sensing an object (O1, O2, O3) in a surrounding area (3) of the motor vehicle (13), with at least one radar sensor (16) having a first transmission antenna (18) for transmitting first transmission signals, wherein the first transmission antenna (18) has a first directional characteristic (20) oriented along a first direction (21) and wherein the radar sensor (16) is designed to sense the first transmission signals reflected from the object (O1, O2, O3) as first echo signals, wherein the first directional characteristic (20) of the first transmission antenna (18) has a null (24) at a predetermined null value angle (25), and the radar sensor device (15) has a control device (17) that is designed to determine an elevation (E) of the object (O1, O2, O3) when the object (O1, O2, O3) enters the null (24) on the basis of the first echo signal and the null value angle (25). The invention also relates to a driver assistance system (14), a motor vehicle (13) and a method.
