A magnetic field measurement system (300), non-transitory computer-readable medium or method can include instructions for, or performance of, actions including receiving output of multiple first magnetic field sensors (302) and multiple second magnetic field sensors (304); and demixing, using the output of the first (N) and second magnetic field sensors (M), at least one signal from at least one target source from signals from other magnetic field sources. The demixing may be performed using a model in which the output of the first magnetic field sensors (N) includes the at least one signal from the at least one target source and that the output of the second magnetic field sensors (M) does not include the at least one signal from the at least one target source.
