Abstract

La invencion se refiere a un metodo de analisis vibrosismico en el cual se emiten senales de barrido de frecuencia en una subsuperficie, las senales reflejadas en los sustratos de dichas subsuperficies son registradas y las senales registradas con procesadas, un metodo en el cual los armonicos de la senal fundamental inicialmente emitida son eliminadas de las senales registradas, al aplicar los pasos que constan de: a) proveer una grafica de tiempo/frecuencia, que muestra las contribuciones respectivas de la fundamental y de los armonicos en la senal registrada; b) proveer una grafica de tiempo/frecuencia que tambien muestre estas contribuciones de la fundamental y de los armonicos en la senal registrada, esta grafica habiendo sido extendida en la direccion del eje de frecuencia de modo que la fundamental de esta grafica este sobre la ubicacion de un armonico seleccionado de la grafica; c) adaptar la amplitud de potencia de esta grafica extendida para hacer que esta amplitud corresponda a aquella de dicho armonico seleccionado de la grafica; d) sustraer estas dos graficas entre si de modo que dicho armonico seleccionado sea eliminado, mediante substraccion con la fundamental de la grafica extendida.
