Abstract : This report details the areas in which signal processing techniques have enabled DSTO Sydney to enhance its existing magnetic testing capability, and present viable data processing options for their implementation. This entails not only accurate sensor calibration, but also calibration of the excitation coils used within the magnetic test system. Reduction of external noise influences through the use of high permeability shielding and filtering are detailed, presenting modelling of coil-shield interactions, and experimental tests for various filter characteristics. Various magnetic coil designs, including DSTO's previously undocumented Ternan coil, are also investigated, leading to the design of a new magnetic coil, the ELFcage coil, being developed. Field uniformity measurements for the Ternan magnetic coil are also presented.
