1. A method for detecting a parking space for a vehicle, comprising:
emitting and receiving radar signals via at least one radar sensor;
evaluating the received radar signals via an evaluation unit to detect a prospective parking space, wherein the evaluating comprises detecting radar reflections from the received radar signal indicating micromovements of a vehicle parked in a parking space; and
identifying the prospective parking space based on the evaluating,
wherein the micromovements comprise one or more of
mechanical vibrations of the parked vehicle associated with a starting of an engine of the parked vehicle,
pitching movements of the parked vehicle about a transverse axis of the parked vehicle in the parked state, and/or
rolling movements of the parked vehicle about a longitudinal axis of the parked vehicle in the parked state.
