Abstract :
An anechoic chamber used for missile test or simulation inherently adds boresite error, generally as a result of sidewall reflections. A simple method of analysis shows this error depends on the sidewall angle of arrival through the antenna difference pattern and the bistatic reflection coefficient of the sidewall material. This material coefficient which is seldom measured is of critical importance.
