METHOD FOR ACQUIRING AND PROCESSING MAGNETOMETRIC DATA BY LOCAL UPDATES IN REAL TIME

摘要

The invention concerns a method for acquiring and processing magnetometric data for representing on an at least two-dimensional map magnetometric characteristics of a geographical zone including a step of measuring the intensity of a magnetic field (1) on a geographical zone producing a set of magnetometric data of intensity B(s), a step of computing 2D interpolation (3), a step of computing reduction at the poles (5) and a step of computing an analytical signal (7). According to the invention, the method includes sectioning the map of magnetic disturbances into a matrix of pixels, a step of locally updating in real time the map of magnetic disturbances, a step of locally updating in real time the map of 2D interpolation by applying the 2D interpolation calculation to the neighbourhood of the updated pixel, a step of locally updating in real time the 2D map of reduction at the poles and a step of locally updating in real time the 2D map of the analytical signal.
