Seismic source/receiver probe for shallow seismic surveying
First Claim
1. A seismic sensor array, comprising;
- a frame comprising ground supports configured to support the sensor array as it is pulled across the ground;
a plurality of discrete probes, each comprising;
a ground engaging member;
a seismic source mechanically coupled to the ground engaging member; and
a sensor assembly mechanically coupled to the ground engaging member and configured to sense ground vibrations resulting from an impact to the ground engaging member by the seismic source; and
a cross member configured to support pivoting mount arms for each probe so that the discrete probes are maintained in substantially fixed relative locations while allowing the probes to individually contact and engage the ground with a consistent force.

Abstract
Systems and methods are implemented for evaluating underground structures and objects, particularly relatively shallow underground structures and objects, using a seismic or acoustic source signal and a resulting seismic or acoustic wave. A discrete or unitary apparatus incorporates both a seismic source transducer and a receiver transducer within a common housing or frame. A unitary seismic probe includes a ground engaging member and a seismic source mechanically coupled to the ground engaging member. The probe further includes a sensor assembly mechanically coupled to the ground engaging member and configured to sense ground vibrations resulting from an impact to the ground engaging member by the seismic source.

13. A method of probing the ground, comprising:
-
moving a frame that supports a plurality of discrete probes across the ground, the frame coupled to a cross member configured to support pivoting mount arms for each probe, each of the probes comprising; a ground engaging member; a seismic source mechanically coupled to the ground engaging member; and a sensor assembly mechanically coupled to the ground engaging member and configured to sense ground vibrations resulting from an impact to the ground engaging member by the seismic source; maintaining, using the pivoting mount arms, the probes in substantially fixed relative locations while allowing the probes to individually engage the ground with a consistent force; contacting the ground with the ground engaging members; generating a seismic or acoustic probe wave using the seismic sources; transmitting the probe wave into the ground using the respective ground engaging members; and sensing, using the respective ground engaging members, ground vibrations resulting from the transmitted probe wave. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
