Anechoic Chamber Evaluation

Author: Karl Haner

This paper details the evaluation of a major aerospace company's tapered anechoic chamber. Using an NSI 3' x 3' near-field scanner and software, the chamber was evaluated at 11 frequencies and two polarizations. SAR imaging techniques were used to map the chamber reflections. A new addition to the software provided the ability to map the difference between the measured phase front and the theoretical spherical phase front; the software also derives the x, y, and z phase centers of the source. Error estimates for all aspects of the evaluation will be discussed.
