Abstract

Se describen métodos y sistemas para extrapolar los campos de onda evitándose al mismo tiempo disrupciones debidas a la alineación espacial; los campos de onda de presión medidos con sensores de presión y campos de onda de velocidad vertical y horizontal medidos con sensores de movimientos tri-axiales pueden alinearse espacialmente en al menos una dirección horizontal; el campo de onda de presión y/o el campo de onda de velocidad vertical están descompuestos en uno de entre un campo de onda ascendente y un campo de onda descendente; el campo de onda ascendente o descendente se extrapola utilizando un extrapolador que depende de los componentes de un vector de lentitud; a fin de evitar disrupciones en el campo de onda extrapolado debidas a la alineación espacial, los componentes del vector de lentitud se calculan a partir del campo de presión medido y los dos campos de onda de velocidad horizontal.
