A radar assembly includes a hollow drum and an antenna holding structure located inside the hollow drum so that the hollow drum can rotate around the antenna holding structure. An antenna is connected to the antenna holding structure and located inside the hollow drum so that the hollow drum can rotate around the antenna. The antenna holding structure is connected to a base frame and to which the hollow drum is connected via at least one axle so that the hollow drum can rotate around the antenna holding structure while the antenna holding structure and antenna remain stationary. A handle is connected to the base frame so that a user can direct the antenna towards a surface of interest which is to be radiated and can then roll the hollow drum over the surface while maintaining the antenna in a user selected orientation.
