Intra-Vehicle Electromagnetic Compatibility Analysis. Part I
Abstract
A computer program was developed to predict and anlyze electromagnetic interference between avionics systems on aerospace vehicles. It is an analytic tool to aid the user in establishing intra-vehicle electromagnetic compatibility. The program is used to derive information which is otherwise impractical or difficult to obtain. This part covers the investigation, research, and development phases of this program. A study of physical principles, previous work, and practical experience identified four predominant interference coupling paths: Antenna-to-antenna, Wire-to-wire, Electromagnetic field (antenna)-to-wire, and Box-to-box. Basic equations and analysis techniques were formulated for each coupling path. These were then assembled into four practical computer analysis programs using FORTRAN IV language. The programs are modular and thus can be run separately or combined into one integral program. This report contains a complete description of each program including the mathematical models, basic equations, and analysis procedures used. Examples of the application of the programs together with sample computer outputs are presented. The programs were developed for the CDC 6600 computer, but they are readily adaptable to other machines.
