Ghosting of TV broadcasting waves caused by skyscrapers in urban areas has become a serious problem. In this paper, we describe method of quickly and effectively measuring the way in which a wall scatters TV waves. The principle of this method is based on the planar near field measurement in antenna technology. A two-element endfire array measures a wall's scattering field at each affected location from the mixed field composed of the main incidence and the scattering field. This paper describes the measuring principle, equipment, and results of experiments using a conducting plate and the wall of a building on our campus. These experiments confirm the effectiveness of this method.
