Title: System and method for surveying underground density distributions
Inventor: TRYGGVASON BJARNI
IPC: G01V11/00
Filed: 2003-06-26
Abstract: A method for geographical surveying includes the steps of determining an observation grid (24) comprising observation points (22) above a solution (1 6) volume in the ground; making gravitational measurements at the observation points (22) over a survey area; compiling a matrix having elements relating a set of gravitational accelerations and gravity gradient values at the points to the mass values for volume elements in the solution volume (16); and calculating the three-dimensional density distribution of the volume under t he survey area based on the gravitational measurements and the inverse of the matrix. By measuring the magnetic field and gradient at the observation points, the three-dimensional magnetic susceptibility distribution of the volume under the survey area can be determined.

In a preferred embodiment, a side residual signal is created as the difference between the side signal and the main signal scaled with a balance factor. The balance factor is selected to minimise the side residual signal.  The optimised side residual signal and the balance factor are encoded and provided as encoding parameters representing the side signal.
