A Two-Dimensional Ray-Tracing Method for the Calculation of Radome Boresight Error and Antenna Pattern Distortion

摘要

A two-dimensional ray tracing analysis for the calculation of radome boresight error and antenna pattern distortion is presented. Emphasis was placed on the development of a method having considerable flexibility, so as to enable application of the method to a wide range of antenna-radome problems, and on relative ease of calculations, so as to minimize calculation time. Several example problems were calculated to demonstrate the usefulness of the approach. Comparisons between calculations and measurements were included whenever measured data were available. Instructions for use of this completely computerized method are included along with several tables describing variables and the complete computer program with necessary subroutines. Programs were written in Fortran IV language suitable for use on the OSU version of the IBM system 360/75 (some minor changes may be required for use on other 360/75 installations). (Author)
