1. An method of tracking an object, the method comprising:
emitting radar signals in successive measurement cycles in a first search window;
receiving radar signals reflected by an object in the first search window;
determining movement information about the object for object tracking on the basis of the radar signals;
determining that a change in the movement information exceeds a limit value in the successive measurement cycles;
determining a second search window wider in the first search window defined on the basis of the movement information in response to determining that the change in the movement information exceeds the limit value in the successive measurement cycles;
emitting radar signals in a subsequent measurement cycle in the second search window; and
tracking the object based on radar signals reflected by the object in the second search window.
