A radar system for sensing object movements in a predefined target area, in particular, for sensing individual objects, accumulations of objects, earth movements, snow movements and the like, comprising: at least one radar unit, which comprises at least one transmitting unit, in particular, transmitting antenna, which is designed to emit electromagnetic radiation, and which comprises at least one receiving unit, in particular, receiving antenna, which is designed to receive reflected electromagnetic radiation; at least one evaluating unit, which is designed, on the basis of the radiation emitted and received and on the basis of associated time measurements, to sense object movements in the predefined target area and to decide for a sensed object movement whether it is a sought-after object movement; at least one covering device, wherein the transmitting unit and the receiving unit are, related to a main radiation direction of the transmitting unit directed toward the target area, arranged behind the covering device or are each arranged behind a respective covering device, in order to protect the transmitting unit and the receiving unit, and wherein at least one clearing device (60; 160; 260; 70) is provided on the radar unit, which is designed to remove deposits, in particular, water, snow and the like, which adhere to or lie on an outer surface of the at least one covering device, wherein the evaluating unit is designed, on the basis of the electromagnetic radiation received, to determine whether deposits are present on the outer surface or not, and to decide whether the clearing device (60; 160; 260, 70) becomes activated or not, and wherein the clearing device is configured as a blower device (60; 160; 260), which is designed to generate a fluid flow (66; 166; 266) along the outer surface of the covering device, in order to remove adhering or adjacent water drops or snow accumulation, characterized in that the blower device and the radar unit are arranged on a common flow component, which includes at least one suction opening (505, 507) through which ambient air enters the flow component and which is configured in such a manner that sucked in ambient air, after redirection by the blower device, exits as a fluid flow along the outer surface of the covering device. at least one radar unit, which comprises at least one transmitting unit, in particular, transmitting antenna, which is designed to emit electromagnetic radiation, and which comprises at least one receiving unit, in particular, receiving antenna, which is designed to receive reflected electromagnetic radiation; at least one evaluating unit, which is designed, on the basis of the radiation emitted and received and on the basis of associated time measurements, to sense object movements in the predefined target area and to decide for a sensed object movement whether it is a sought-after object movement; at least one covering device, wherein the transmitting unit and the receiving unit are, related to a main radiation direction of the transmitting unit directed toward the target area, arranged behind the covering device or are each arranged behind a respective covering device, in order to protect the transmitting unit and the receiving unit, and wherein at least one clearing device (60; 160; 260; 70) is provided on the radar unit, which is designed to remove deposits, in particular, water, snow and the like, which adhere to or lie on an outer surface of the at least one covering device, wherein the evaluating unit is designed, on the basis of the electromagnetic radiation received, to determine whether deposits are present on the outer surface or not, and to decide whether the clearing device (60; 160; 260, 70) becomes activated or not, and wherein the clearing device is configured as a blower device (60; 160; 260), which is designed to generate a fluid flow (66; 166; 266) along the outer surface of the covering device, in order to remove adhering or adjacent water drops or snow accumulation, characterized in that the blower device and the radar unit are arranged on a common flow component, which includes at least one suction opening (505, 507) through which ambient air enters the flow component and which is configured in such a manner that sucked in ambient air, after redirection by the blower device, exits as a fluid flow along the outer surface of the covering device.
