Abstract
A method for detecting a subterranean anomaly is provided. The method includes receiving signal data derived from a plurality of transmitters and at least one receiver; calculating a relationship for selected combinations of measurements provided by the signal data; estimating weighting factors for each transmitter, for a condition where there is a substantially equivalent potential across each of the transmitters; applying the weighting factors to the data; and identifying the anomaly in weighted data. Apparatus are also provided.
