Viability of Convez-modulated Ezponential Serraions for Improved Performance of CATRs
Compact Antenna Test Range Reffector (CATR) offers many advantages over other types of ranges and consequently a lot of effort is being directed towards the improvement of compact range performance. CATR performance can be further improved by using serrations. Serrating the edges of the reffector in order to redistribute the diffracted rays in many directions away from the test zone area. Application of serrated edges has been shown to be a good method to control diffraction at the edges of the reffectors. Serrated edge CATR is used to reduce the diffraction effect. However, in order to get some insight into the positive effect of serrated edges a less rigorous analysis technique known as Physical Optics (PO) may be used. In this paper, the sides of the reffector are considered to be equipped with convex-modulated exponential serrations. Fresnel zone field is evaluated at a distance of 64λ From the reffector surface. Ripple free and enhanced quiet zone width are observed for specific values of width modulation factors
