A radar system for sensing object movements in a predefined target region is described. The radar system includes: at least one radar unit which includes at least one transmitting unit designed to emit electromagnetic radiation and at least one receiving unit designed to receive reflected electromagnetic radiation; at least one evaluating unit designed to sense object movements in the predefined target region and, for a sensed object movement, to decide whether the object movement is a sought object movement; at least one covering device behind which the transmitting and receiving units are arranged for protection; and at least one clearing device designed to remove deposits that adhere to or lie on an outer surface of the at least one covering device. The evaluating unit is designed to determine whether deposits are present on the outer surface or not and to decide whether the clearing device becomes activated or not.
