Abstract

Al menos algunas modalidades se dirigen a un sistema; el sistema incluye un procesador un una memoria acoplada al procesador; la memoria almacena un programa que, cuando se ejecuta por el procesador, causa que el procesador calcule una respuesta de presión de un primer sensor, y datos correctos de campo ondulatorio de presión obtenidos del primer sensor que responde a un primer campo ondulatorio acústico; la corrección se basa en la respuesta calculada de presión del primer sensor; la respuesta de presión del primer sensor responde a un segundo campo ondulatorio acústico que tiene una trayectoria de propagación entre una fuente del segundo campo ondulatorio acústico y el primer sensor, en el cual la trayectoria de propagación no incluye reflexión de una formación subsuperficial.
