Abstract

An electric-field cross-correlation Fourier transform spectrometer worked in the region of millimeter waves is described. It uses two controllable phase variation pseudorandom binary sequences (PRBS) to modulate individually two microwave fields devived from the same source, so two wide bandwidth microwave signals with variable phane delay are obtained. The Fourier transform of the cross-correlation function of these microwave signals is the cross-power spectrum. The principle and fundamental structure of the spectrometer are presented and experimental results are given in 8mm-wave range.
