STATIONARY STAR SHAPED ANTENNA METHOD FOR MANIPULATING FOCUSED BEAMFORMED, SHAPED FIELDS AND BEAMSTEERED ELECTROMAGNETIC SIGNALS FROM SUBTLE SEDIMENTARY STRATIGRAPHIC FORMATIONS DEEP IN THE EARTH
摘要
<p>A method for electromagnetic geophysical surveying according to one aspect of the invention includes disposing a plurality of electromagnetic receivers in a selected pattern above an area of the Earth's subsurface to be evaluated. An electromagnetic source is repeatedly actuated proximate the electromagnetic receivers. Signals generated by the receivers, indexed in time with respect to each actuation of the at least one electromagnetic energy source, are recorded. The recorded signals are processed to generate an image corresponding to at least one point in the subsurface. The processing includes stacking recordings from each receiver for a plurality of actuations of the sources and beam steering a response of the receivers such that the at least one point is equivalent to a focal point of a response of the plurality of receivers.</p>
