1. An angle-resolving radar sensor, comprising:
a receive antenna having multiple receive antenna elements which are each switchable to at least one of multiple evaluation channels, wherein a first evaluation channel to which a first receive antenna element is switchable is different than a second evaluation channel to which a second receive antenna element is switchable, and wherein at least one of the first and second receive antenna elements is switchable to both the first evaluation channel and the second evaluation channel;
a switching device to connect the evaluation channels alternatingly to different selections of receive antenna elements; and
an evaluation device for determining an angle of incidence of a received signal based on amplitudes measured in the evaluation channels;
wherein the number of receive antenna elements is greater than the number of evaluation channels.
