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. A signal source provides a signal having a first frequency to an input of the antenna. Each of the antenna's scattering elements are individually selectable to radiate the signal. A control signal sequentially turns off and on each scattering element while radiating the signal. Also, a characteristic of the signal radiated 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.
