Multilayer R-Card fence design for ground bounce reduction

Multilayer R-Card fences have been designed and evaluated for an outdoor range in order to reduce the ground bounce effects. This design not only can reduce the specular reflection by the ground to the receiving area but also reduce the reflection back to the transmit area due to the corner reflector effects. It has been found from the previous and current studies that tapered R-Card fences can very effectively used in reducing multipath stray signals, such as the ground reflection term in an outdoor range. With available commercial resistive sheets, these fences can be built very inexpensively and has great potential in many other applications.
