ABSTRACT:
In order to decrease the interfering reflection of radar radiation from building walls during radar surveillance on the ground, the outer walls are formed on their surfaces so that the reflected radar waves are subjected in part to a phase shift of one half wavelength with respect to each other. This results in a partial obliteration of the reflected waves. The reflecting surface of the outer wall comprises for that purpose of individual elements whose superficial extent is smaller than the surface irradiated by a radar impulse, and which are staggered in depth in such manner that adjoining surface elements are located at a distance from each other which is equal, for perpendicular incidence of the radar radiation, to one quarter wavelength of the radar radiation used.
