A detection-system for a vehicle to detect the presence of one or more object relative to the vehicle comprises a module-housing, a radar sensor component located within the module-housing for emitting a radar beam and receiving reflected signals in a detection mode. The radar sensor component comprises means for emitting a defrost beam in a defrost mode; the defrost beam overlapping the radar beam. The detection-system further comprises an absorber material located in the field of view of the defrost beam to absorb the energy of the defrost beam and to warm up in view to provide a defrosting effect.
