A mobile magnetometry processing system which scans an area in order to measure the magnetic field strength over the area, comprising a plurality of N sensors for sensing the magnetic field of the rea being scanned, each sensor generating an output signal, for example, a voltage, which is a function of the magnetic field it scans, the sensor being aligned in the general direction of the motion of the system a plurality of N sets of means for weighting, for receiving and weighting the N signals from the means for sensing, each of the N sets comprising M weighting means a plurality of M summers, each have N inputs, one from each of the N sets of means for weighting, for summing its N input weighted signals and a plurality of M filters each having an input which is connected to the output of a summer, for delaying the exit of an input signal by an amount of time equal to the time required for a sensor to advance the distance to the nearest adjacent sensor, the filtering process comprising a convolution.
