A correlation processor based on the excellent periodic autocorrelation properties of maximal-length pseudorandom binary sequences has been used in antenna pattern measurements to resolve the direct (wanted) path from any unwanted multipath components. A simple implementation of the technique has been used to make measurements in a controlled environment; the results show that the multipath effects are almost completely eliminated and an accurate pattern measurement is obtained.
