发明名称 Angular resolution radar sensor
摘要 A radar sensor having multiple antenna elements for transmitting and receiving radar signals, an associated transmitting and receiving element and an evaluation device for determining the azimuth angle of located objects on the basis of a relationship between the signals received from different antenna elements, wherein the transmitting and receiving element is designed to supply to the antenna elements transmission signals in parallel, the frequencies of which are offset with respect to one another, and the evaluation device is designed to distinguish between signals that were transmitted by different antenna elements on the basis of the frequency offset.

主权项 1. A radar sensor, comprising: multiple antenna elements adapted to transmit and receive radar signals; a transmitting and receiving element; and an evaluation device adapted to determine an azimuth angle of located objects based on a relationship between signals received from different ones of the antenna elements; wherein the transmitting and receiving element is adapted to supply to the antenna elements transmission signals in parallel, the frequencies of which being offset with respect to one another, and the evaluation device is adapted to differentiate between signals that were transmitted by different ones of antenna elements based on the frequency offset, and wherein the magnitude of the frequency offset for at least one of the antenna elements is at most equal to the smallest of the transmitting frequencies supplied to the multiple antenna elements.
