dc.description.abstractMultipath on far-field antenna ranges causes distortion of antenna pattern measurements: The multi path components have differing path lengths and hence can be separated by illuminating the antenna under test with short-duration pulses. Alternatively, antenna measurements can be made in the frequency domain, and the Fourier transform can be used to relate the frequency-domain measurements to the antenna's time-domain response. The interference then can be removed with a time-domain gate, and transformed back into the frequency domain to yield improved CW antenna patterns. Virginia Tech has recently completed a major upgrade of their far-field antenna range and implemented a system to perform this data collection and data processing. This thesis describes the principles and implementation of the time-domain processing part of the system. Further, it demonstrates the validity of the method by showing the improvements in pattern measurement that have been achieved with the new system.en
