In seismic signals processing
specifically in seismic signal filtering
two classes of signals are distinguished; first type of signals are related to useful information about subsoil layers
the second type of signals are related to noise captured in seismic exploration records
often known as Ground-Roll. Previous research show that such two type of signals can be separate
measurably
if they are analyzed on a time-frequency domain. Furthermore
some research state the two type of signals have different polarization behaviors
the first one often have linear behaviors whereas the second one have elliptical behavior. In this undergraduate work
it’s proposed a couple of modifications to the filter presented in [1]
which is a polarization filter based on the spectral matrix [2] and the S transform that attenuates the Ground-Roll in seismic signals. The proposed modifications in this works are based on the expansion of the spectral matrix in non-disjoint idempotent matrices and on the change of the polarization and ellipticity attenuation functions described in [1]. Therefore
in this work it’s determined the effectiveness of the proposed modifications by the filtering of a synthetic signal and the construction of some cost functions that allows to compare objectively the filters
the filter presented in [1] and the modifications proposed in this work.

description |
En el procesamiento de señales sísmicas, específicamente en el filtrado de las mismas, se distinguen dos tipos de señales, el primer tipo de señales corresponden a la información útil de las capas del subsuelo, el segundo tipo de señal se relaciona al ruido captado en la exploración sísmica, conocido como Ground-Roll. Investigaciones previas demuestran que estos dos tipos de señales se pueden separar en cierto grado si se analizan en algún dominio tiempo-frecuencia, además también argumentan que los dos tipos de señales tienen características diferentes de polarización. En este trabajo de grado se proponen un par de modificaciones al filtro presentado en [1], el cual es un filtro de polarización basado en la matriz espectral [2] y en la transformada S para la atenuación de Ground-Roll en señales sísmicas. Las modificaciones propuestas en este trabajo se basan en el cambio de las funciones de atenuación de polarización y elipticidad descritas en [1], y en el uso de la expansión de la matriz espectral en matrices idempotentes no disyuntas. Así, en este trabajo se determina qué tan efectivas resultan las modificaciones, a partir del filtrado de una señal sintética y la construcción de unas funciones de costo que permiten una comparación objetiva sobre los filtros, el presentado en [1] y las modificaciones propuestas en este trabajo. |
