<p>A method and apparatus (10) for collecting measurements on the surface of the earth in a form which can be processed to obtain enhanced resolution of subsurface resistivity anomalies in the earth's geologic structure. The system of the preferred embodiment utilizes manu separately acquired voltage (14 and 14') and current (12, 12' and 12'') measurements on the earth's surface in a superposition analyzing system (20) to ''synthesize'' the condition whereby the many separate measurements are acquired simultaneously to give useful advantages in improved depth of investigation commonly known as focused resistivity measurements.</p> |
