High-Sensitivity Subsurface Sensing System
The system uses orthogonal antennas and rotation of the beam about its axis to preserve the primary coupling while changing the target coupling. The beam may be either vertical or horizontal. The prototype system currently has a dynamic range of 134 dB, with an expected increase to over 200 dB when a TX moment comparable to that of current commercial...
