Abstract
A dipole moment detection and localization process and apparatus in which the processing is applied to a single linear array adapted to sense magnetic dipoles, and wherein data from the sensors are processed as if it were derived from sets of subarrays of sensors. The apparatus comprises a linear sensor array whose output is processed by separate dipole moment detection and location processors, or a single processor that provides for parallel processing operation. Data from the plurality of subarrays of sensors are processed in terms of Anderson functions and are correlated. The individual outputs of each processor, or parallel processing portion, is coupled to a multiplier that is adapted to correlate the signals. The dot product of these two correlated output signals is then formed to yield data that is thresholded and displayed.
