Locating sources of reflection errors in an anechoic chamber by creating an error surface plot

A technique to locate sources of reflection errors in an anechoic chamber is presented in this article. This technique expands the NIST 18 term error analysis method and compares reflections over the whole sphere instead of using only cuts which are the proposed method of analysis. Reflection errors are consequently portrayed as an error surface. These error surfaces are displayed with surface plots and can be used as a tool to locate the origin of reflections.
