Abstract
A method for operating a radar sensor device, for example of a motor vehicle, including a plurality of transmitting antenna elements and a plurality of receiving antenna elements, where at least a part of the antenna elements are situated along an arc and/or intersecting planes and where the antenna elements are divided into a plurality of antenna systems that each includes at least two of the transmitting antenna elements and at least two of the receiving antenna elements, includes: operating each of the antenna systems as an independent multiple-input-multiple-output radar system, the operating including: transmitting transmit signals using the transmitting antenna elements that are of first and second ones of the antenna systems, whose transmission ranges overlap and whose transmit signals are orthogonal to one another; and receiving reflections of the transmitted transmit using the receiving antenna elements.
