摘要：
UTD method in the case of the source on convex surface is used in the analysis and design of antennas especially conformal arrays on electrical large platforms, a creeping ray tracing algorithm of UTD method is given in this paper with the source on arbitrary convex surface, the Non-Uniform Rational B-splines (NURBS) surfaces are introduced to model the targets, due to the fact that most CAGD softwares used in industry are based on NURBS, method presented here need riot to rebuild the targets. The algorithm given in this paper can be applied to arbitrary surfaces, the validity and usefulness can be seen form numerical results.
