METHOD AND SYSTEM FOR OBTAINING HIGHER ORDER GRADIOMETER MEASUREMENTS WITH LOWER ORDER GRADIOMETER

摘要

A method and system of obtaining magnetic measurements with a preselected order of sensor gradiometer which are substantially equivalent to those which would be obtained with a sensor gradiometer of a higher order. The system and method employs a reference system comprising a reference tensor gradiometer and appropriate components of a measured tensor are combined with the measurements obtained from the sensor gradiometer to obtain a magnetic measurement substantially equivalent to that which would have been measured by a higher order sensor gradiometer.
