Abstract

A method of processing seismic survey data to identify objects buried close to the surface in a region of interest comprises extracting surface wave data from the seismic survey data, processing the surface wave data to identify areas in which buried objects are not located, extracting p-wave data from the seismic survey data for the areas in which buried objects are located, and processing the p-wave data for the areas in which buried objects are located to identify the buried object. The object may be an IED (improvised explosive device). The p-wave data may be used to determine velocity signatures for grid cells representing areas in which buried objects are located, and the velocity signatures may be used to identify characteristics of the buried objects. Electromagnetic survey data may additionally be used to determine conductivity and/or attenuation signatures. Also disclosed is a tomographic post comprising a seismic source located in a chamber between inner and outer housing, wherein the chamber is pressurised with an inert gas.
