Yang Xuhui · Geophysical and Geochemical Exploration · 2010
Pseudo-random signal has been widely used in seismic exploration because of its excellent auto-correlation.This paper has deeply studied the important parameters related to the auto-correlation function of pseudo-random signal with the purpose of improving auto-correlation function properties of the pseudo-random signal.An analysis of the simulation results has revealed the relationship of the carrier frequency and primitive polynomial order to the autocorrelation function.The length of the pseudo-random scanning signal and the principle for the choice of the amplitude are also given in this paper.
