摘要： The present invention relates to a HTEM system that includes a semi-rigid bucking coil and an algorithm to determine the magnetic field B from the measured signal dB/dt. The bucking coil may be positioned in a concentric coplanar manner relative to a transmitter coil and receiver coil, in order to minimize spurious signals at the receiver coil during data acquisition time. Signals gathered by the system may be further processed by a signal processing means. Moreover, measurements performed upon data generated by the system may be performed upon the entire period of a current waveform applied to the transmitter and bucking coils.

摘要： The present invention is a double-suspension receiver coil apparatus and system for conducting electromagnetic surveys including, both ground-based and airborne measurements. The present invention includes at least one receiver coil suspended by way of first suspension members within an inner frame and said inner frame being suspended by second suspension members within an inner ring which is further enclosed within an outer frame. The double-suspension receiver coil apparatus functions so as to maintain the receiver coil position while minimizing vibrations in order to achieve a high signal-to-noise ratio and enable accurate measurements. The receiver coil may be in an airborne system in a near-horizontal position or in a ground system in a vertical position.
