Quiet Zone Diagnostics in a Microwave Anechoic Chamber Using Imaging

A quiet zone (QZ) diagnostic technique for a microwave anechoic chamber has been demonstrated. It provides a comprehensive imaging view of the QZ's performance. The imaging for reflected signals from different angles and direct signals within the QZ provides the location of strong reflected signals accurately. This technology can perform a specific diagnosis of the QZ after it is found that the performance of the quiet zone does not meet the design requirements.
