Abstract
It is often required to find “smooth” analytic representations for antenna reflector surfaces which are prescribed only by discretized data obtained by various synthesis methods. Frequently the data are distributed in a nonuniform grid and contain noise. The “smoothness” required is to C, for physical optics diffraction analysis and to C, for Geometrical Theory of Diffraction (GTD) analysis. Furthermore, the GTD analysis approach requires a surface description which returns data very rapidly. Two methods of interpolation, the global and the local methods, are discussed herein. They each have advantages and disadvantages — usually complementary. These characteristics are discussed and examples are presented.
