Th. Lee et Wd. Burnside, PERFORMANCE TRADE-OFF BETWEEN SERRATED EDGE AND BLENDED ROLLED EDGE COMPACT RANGE REFLECTORS, IEEE transactions on antennas and propagation, 44(1), 1996, pp. 87-96
The performance trade-off between serrated edge and blended rolled edg
e compact range reflectors is investigated. The edge diffracted fields
which contribute to stray signals in the quiet zone have to be minimi
zed. Consequently, an iterative approach has been developed to design
serrated edges such that the edge diffracted rays from the serrations
can be kept as far away as possible from the desired quiet zone area,
Performance of various designs based on the number and size of serrati
ons have been studied using a physical theory of diffraction solution,
In addition, an optimized blended rolled edge design with the same si
ze as the serrated edge reflector has also been evaluated for comparis
on, Finally, numerical results are presented in this paper to address
the performance trade-off issue among the various designs, It is clear
ly shown from this study that the blended rolled edge reflector perfor
ms significantly better, which should offset the increased cost needed
to construct a rolled edge reflector versus a serrated one.
