基于三元伪随机编码的可控震源信号设计方法
Vibroseis signal designing based on ternary pseudorandom coding technology
摘要
Abstract
In seismic acquisition if regular linear scanning signal is used for the vibroseis, seismic response will show large sidelobes and the resolution for the seismic response will be low, if using dualistic pseudo-random code as scanning signal for the vibroseis, the severe noise will be generated in seismic response section and the signal-to-noise ratio will be decreased. In this paper the ternary pseudorandom series with ideal correlation characteristics was used to design vibroseis signal coding, the numerical simulation for seismic response shows that if using the ternary pseudo-random coding technology much more noise in the seismic response was eliminated compared with using dualistic pseudorandom coding so that the seismic signal-to-noise ratio was greatly improved on the seismic response section.关键词
