Abstract
A system for evaluating the performance of beam forming antennas based on correlations of signal to noise measurements of individual scattering elements in the antennas. An RF source provides a radio frequency (RF) signal having a first frequency to an input of the antenna. Each of the antenna's scattering elements are individually selectable to emit the RF signal. A bias signal sequentially turns off and on each scattering element while emitting the RF signal. Also, a characteristic of the RF signal emitted by each scattering element is separately measured and each difference between the characteristics are identified and compared to one or more threshold values. A report regarding the differences that exceed the threshold value is provided to a user.
