Being a certain information pertaining to stochastic process, SIGN-BIT has been introduced into the field of seismic receiving. In America, SIGN-BIT seismic acquisition systems manufactured by GEOSYSTEM CORP. have been put into use. Its basic theory was presented at the 49th SEG International Annual Meeting.

符号位——作为一种随机过程信息已被应用于地震信号的接收。美国地球系统公司有产品投入生产,其基本理论已于SEG49届年会上发表。本文将对此基本理论略加补充并以明显的数据论证其应用的可能性和局限性,更以美国地球系统公司生产的符号位地震仪——GEOCORⅣ的建立和发展为例,评述该仪器的性能。最后提出如何在地震信号接收中正确应用符号位信息接收理论的设想。

To begin with, the notch filtering, low-pass filtering and correlation effects in seismic receiving systems are discussed through analyzing their filtering characteristics. After introducing a seismic noise factor, analysis on the applied conditions for high-resolution, stack array and enhanced receiving systems is made in the context of optimizing acquisition filters and the method to selecting seismic receiving parameters with a nominal noise level as constraints is also presented. The practical effect is eventually demonstrated with applied examples.

本文首先从地震接收系统的滤波特性入手,论述了接收系统的陷波效应、低通滤波器效应和相关效应.接着引入地震噪声因素,从野外滤波最佳化的角度分析了高分辨率接收系统、叠加组合法接收系统和强化接收系统的应用条件,给出了以噪声强度为约束条件设计地震接收参数的方法.最后以实例展示了应用效果。

Based on higher order statistics property containing signal phase information, fourth order cumulant and its fourth order spectral on the seismic received signal, a novel approach for estimating non minimum phase seismic wavelet is proposed. It can be fully reconstructed from the fourth order spectrum by only spectral decomposing the seismic wavelet into minimum phase and maximum phase in arbitrary Gaussian environment. Computer simulation demonstrates its effectiveness. [

利用高阶统计包含信号的相位信息特性 ,并基于信号的四阶累积量及其四阶谱 ,提出一种地震信号的非最小相位子波的估计方法 .在任意高斯噪声环境下 ,对地震子波进行最小相位和最大相位谱分解 ,两部分信息完全可以从四阶谱中恢复 .计算机数值模拟实验证实了方法的有效性
