Inventors:

Ronald Helms - Vienna VA, US

International Classification:

Appl. No.:

7/037052

Inventors:

Ronald L. Helms - Oakton VA
Claude V. Swanson - Reston VA

International Classification:

G01V 308
G01W 116
G01R 1900
G01R 2300

US Classification:

324323

Abstract:

A method and apparatus for locating and evaluating surface and subsurface anomalies by detecting, monitoring or measuring transient or local variations respectively which occur in an alternating component of a vertical current having a frequency characteristic which emanates from the earth'surface in the region being monitored or measured. For locating fixed anomalies, local variations which occur in the amplitude, frequency and frequency modulation of the alternating component of the vertical current are measured. For detecting the passage of moving or transient anomalies, a stationary detector is positioned to detect any change in the vertical alternating current leakage in the vicinity of the detector which is caused by a moving or transient anomaly such as a submerged submarine, seismic activity, or sustained severe wheather. For accuracy enhancement and redundancy, simultaneous measurements of the signal strength in multiple frequency bands may be used.

G01R 1900
G01R 2300

US Classification:

324323

Abstract:

A method and apparatus for passively determining the depth of an anomaly using means for monitoring a broad spectrum of frequencies and analyzing the amplitude and modulation of a time and/or location varying signal within discrete bands of frequencies to determine the depth of a spatial or temporal anomaly. A means for recording and mapping substerranean features based on an ascending or descending sequence of frequency measurements is also disclosed.

International Classification:

G01V 315

US Classification:

324323

Abstract:

A method for locating and evaluating surface and subsurface anomalies. Solar wind results in a multi-frequency, high energy ionic impingement at the terrestrial poles of the earth. Monitoring the activity of the solar wind allows the determination as to when the activity produces a vertical alternating current leakage (solar alternating current) due to the ionic impingement. When the vertical current leakage is in a proper range which can be measured and which reflects and represents surface and subterranean anomalies, a predetermined region of the earth to be prospected is traversed. Local variations which occur in the amplitude, frequency and frequency modulation of the vertical alternating current leakage due to the ionic impingement of solar winds at the terrestrial poles (solar alternating current) is measured. The measurements are recorded in correlation with the spatial relation to the points of measurement to determine significant measurements indicative of surface and subterranean anomalies.
