To meet the technical requirements of missile radome frequency selective surface (FSS), a partition and projection system of radome surface was proposed and developed. Based on the study of approximate partition and projection of complex surface, the partition coefficient was defined as the ratio of the integration of the absolute value of Gaussian curvature to its area, and the controlling value for surface partition is the summation of partition coefficient of the accumulated surface elements; the surface partitions was projected into 2D shapes by using cross baseband expansion method. On the basis of the above algorithms and data operation, an application framework was developed by using MFC, and the surface data operation was visualized with OpenGL. The surface projection data can be exported into AutoCAD format for subsequent fabrication. A successful application for a missile radome surface demonstrates that, the partition/projection method has high accuracy and satisfies the design requirements.
