| 摘 要： | 论文首先指出了利用野外试验记录和一维谱资料分析地震噪声的局限性,提出了利用频波谱(简称f-k谱)分析地震噪声的观点.接着以实例详细论述了f-k谱在研究噪声特征、为二维滤波提供最佳参数和分析野外工作参数的地质效果等方面的应用方法.实践证明,f-k谱为分析和衰减地震噪声提供了定量的依据,对指导野外采集和资料处理,提高地震资料的信噪比和分辨率有一定的参考价值.

| Abstract: | This paper first points out the limitations of applying field test records and one-dimensional-spectral data to the analysis of seismic noise, and suggests frequency wave spectra(f-k spectra)to the analysis of seismic noise. Then, with practical examples,it deals in detail with the apPlication of f-k spectra in such aspects as the study of noise characteristics,the providing of optimum parameters for two-dimensional wave-filtering, and the analysis of geological effecters.field work parameters. practice shows that f-k spectra provide quantitative basis for the analysis attenuation of seismic noise, and are hence of some referential value in guiding field collection and data processing as well as raising the signal-to-noise ratio and resolution ratio of seismic data. |
