ABSTRACT:
The technologies of radar, exploration seismology, and air or space transportation, are combined to provide a highly-mobile and economical system of geophysical exploration for petroleum and other mineral deposits. Use is made of the Seismo-electric (SE) and Electro-seismic (ES) effects to momentarily alter the reflection and scattering from, and absorption in, the earth's surface, of electromagnetic (radar) waves transmitted from, and received by, an aircraft or space vehicle, to thereby modulate seismic information on the reflected, scattered and received waves. In this improvement, the received waves, as represented by their transduced electric counterparts, are divided into two paths having different times of transmission, and synchronously re-combined to enhance systematic or meaningful information and remove non-systematic disturbances and random noise.
