Tīmeklis2002. gada 1. aug. · Abstract Focusing on a comparison of the accuracy of the extended spatial autocorrelation (ESAC) method and the frequency–wavenumber spectrum (FK) method, we carried out short-period microtremor measurements of arbitrarily shaped array configurations at a site with a well-known velocity structure at shallow depths. Tīmeklis2014. gada 1. aug. · A popular method for the analysis of seismic ambient noise is the modified frequency–wavenumber (fk) algorithm proposed by Capon which has high … Tīmeklis2015. gada 18. febr. · To enhance the signal-Noise ratio different techniques are used to remove the noises. Types of Seismic Filtering: 1- Frequency Filtering. 2- Inverse Filtering (Deconvolution). 3- Velocity Filtering. Frequency Filtering Basically seismic data processing is done in the frequency domain.
