Abstract:
1. An antenna array for a radar sensor, comprising: a number of antenna elements linearly arranged next to one another and designed for transmitting or receiving a radar signal; a transmitting or receiving unit; and a switching unit, designed to connect said antenna elements individually one after the other in time with said transmitting or receiving unit according to a predetermined switching sequence, wherein: the switching sequence, according to which said antenna elements are connected one after the other with said transmitting- or receiving unit, deviates from the spatial sequence of said antenna elements in the antenna array, the received signals associated with said antenna elements corresponding to the switching sequence have, in each case, a phase, which includes a phase contribution caused by the angular position of the target and a phase contribution caused by the velocity of the target; and the switching sequence is determined in such a manner that the phase contributions caused by the velocity of the target change in sign along the arrangement of said antenna elements from one antenna element to a neighboring antenna element.
