Abstract:
The performance trade-off between serrated edge and blended rolled edge compact range reflectors is investigated. The edge diffracted fields which contribute to stray signals in the quiet zone have to be minimized. 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 serrations have been studied using a physical theory of diffraction solution. In addition, an optimized blended rolled edge design with the same size as the serrated edge reflector has also been evaluated for comparison. Finally, numerical results are presented in this paper to address the performance trade-off issue among the various designs. It is clearly shown from this study that the blended rolled edge reflector performs significantly better, which should offset the increased cost needed to construct a rolled edge reflector versus a serrated one.
