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 preselectedorder of sensor gradiometer which are substantially equivalent to those whichwould be obtained with a sensor gradiometer of a higher order. The system andmethod employs a reference system comprising a reference tensor gradiometerand appropriate components of a measured tensor are combined with themeasurements obtained from the sensor gradiometer to obtain a magneticmeasurement substantially equivalent to that which would have been measured bya higher order sensor gradiometer.
