Abstract:

These Extra Low Frequency ELF coils for measuring low frequency magnetic signatures were designed and built for use with the Marine Environment Data Acquisition System MEDAS concept demonstrator. This report details the tests conducted to determine the performance of these coils. A circuit model of the ELF coils is developed so the output of the coils may be related to the incident magnetic field. The values for the resistance, inductance and capacitance are measured and calculated from details of the construction. The effect of incorporating a calibration winding for checking the in-situ underwater response of the ELF coils are also examined.
