This paper describes a particularly manufactured measuring device for ship magnetic signature and presents a statistical analysis of the measured data. A novel method specific to this type of magnetic measurement is developed and applied to the available data. There are analyzed the sources of uncertainty that affect the measurement and there is developed a specific model for the assessment of the uncertainty in magnetic field measurements with fluxgate transducers. Based on the operating principle of the fluxgate magnetometer, there were identified the main sources of uncertainty and their impact on measurements was computed. Finally, the resulting magnetic signature is reported as a value range determined by the combined uncertainty.
