Comparison of Reflective Properties of Corner Reflector Clusters and Luneburg Lens Reflectors

摘要

The reflective properties of rectangular corner reflector clusters and Luneburg lens reflectors are analyzed, and the relative effectiveness and efficiency of these reflectors in producing large radar cross sections over a wide range of aspect angles is compared. The Luneburg lens reflector is found to be very effective and efficient, but is expensive, heavy, and difficult to repair. In contrast, the rectangular corner reflector cluster is inexpensive, repairable, and can be made lightweight, but is not an efficient reflector when used over wide ranges of aspect angles. (Author)
