可控震源伪随机扫描信号的仿真研究
|
摘要
伪随机序列具有良好的的自相关函数,在地震勘探中具有广阔的应用前景,从提高伪随机扫描信号自相关函数性能出发,着重分析了与伪随机扫描信号自相关函数密切相关的重要参数。通过对仿真结果分析得出了载波频率及本原多项式阶次与其自相关函数之间的联系,并给出了伪随机扫描信号长度及幅值的选择原则。
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.
