Abstract
A method and device for vehicle-supported object detection. A pulse is emitted into the surroundings using a transducer situated in a vehicle, and the pulse, which is reflected back by an object in the surroundings, is recorded using the transducer. The transducer and the object move relative to each other. The emission and/or the recording are carried out according to a directional characteristic of the transducer, which has at least two directional lobes. Signal components of the reflected pulse, which have different frequency shifts, are separated from one another on the basis of the frequency shift or are assigned to respectively one of the directional lobes. An object detection is carried out in each case for the different signal components and the assigned directional lobes.
