Practical validation of antenna pattern measurement interference cancellation using a correlation technique

Antenna pattern measurements are often distorted by extraneous signals that reach the test zone as a result of reflections or scattering from obstacles in the vicinity of the antenna range. These "multipath" signals have to be eliminated, or their effects compensated, if accurate measurements are to be made. In this paper, the ability of correlation techniques to suppress multipath signals that cause inaccuracies in antenna pattern measurements has been validated by experiment.
