Compact Range Evaluation by GTD Modelling

16 Nov 2008

A compact antenna test range has been analysed for stray signals. The analysis is based on GTD ray tracing, i.e. obeying the reflection law in the chamber walls and assuming straight edges of reflectors and walls. Comparisons to an RCS as well as a time domain measurement of the quiet-zone performance show good agreements with respect to identification of the ray paths of the stray signals. Rough estimates of the power loss at reflections and diffractions show acceptable agreements with the measured levels.
