摘要：The protective wall (10) consists of a single layer, or a sandwich of soil or building materials. It has an extra, spaced material layer (13) of solid material, or vegetative components (12) on the side exposed to a radar impingement for narrow band reflection suppression according to the interference principle. The spacing (11) of the extra material layer is so rated that it can be penetrated by the vegetative components and optically covered. The extra material layer may consist of a metal grid, possibly construction steel with plastics coating, with a mask between 3-20 cm. It may consist of a nylon knitted fabric. USE/ADVANTAGE - Aircraft protection installations, without causing interference to directional radio paths or safety systems by undesirable reflections.
