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.

Abstract: The invention relates to a seismic system having an array of nodes, each capable of emitting and detecting seismic signals. The array of nodes is mounted on a mobile platform in a certain geometry and is configured to acquire subsurface data, and more particularly detect shallow buried objects, while being translated over a surface. Such a seismic system allows for high subsurface point redundancy by providing a large number of channels of data used to sum the energy at a point in the subsurface. In other aspects, the invention relates to methods for processing the acquired data to increase signal-to-noise ratio. In still other aspects, the invention relates to methods for imaging the data for visualization on a display.

Abstract: A system and method for reducing acoustic, wind or other background noise that may interfere with sensing of a seismic signal is provided. More specifically, a shield is provided to enclose a geophone and thereby protect it from harmful noise. The shield may comprise a rigid shell, a structural damping material, an acoustically absorptive material, and a compliant seal for coupling the shield to the ground or reference surface.
