Abstract

The oscillations in the antenna extrapolation measurement data due to multiple reflections between the antennas have proved difficult to fit accurately by the least squares procedure. This report describes a method for digitally filtering the data prior to fitting to remove these oscillations. A Pascal program has been written to perform the filtering and the process has been shown to be effective.
