A Rolling Line Source for a Seismic Sonar

Abstract

This thesis builds on ideas of a seismo-acoustic sonar as a mine detection tool and is part of an ongoing Naval Postgraduate School (NPS) research project. Building on this foundation of research, a source was developed to enable mobility. The previous NPS array Sheetz design employed an array of sources, buried in the sediment in a line. This arrangement is somewhat cumbersome for direct application. A practical device should be mobile and create a high source signal similar to the previous NPS array. A rolling cylinder provided the solution. The cylinder houses two shakers, identical to the previous NPS array elements, mounted directly to the cylinder wall. The source for a single buried array element, from the previous NPS array, and a single rolling cylinder, placed on the surface, were shown to provide similar seismic velocity at ten meters range.
