A data acquisition system has been assembled using Micro-Electro-Mechanical Systems (MEMS) technology which provides a flexible data gathering capability to support recording accelerations at various locations within a sand filled 5 meter square test pit that has a depth extending into underlying gravelly soils. Dual-axis accelerometers weighing less than 1 gram each, made possible by advances in MEMS technology, are connected to up to 5 data acquisition (PXI modules) boards, each capable of controlling and recording data from 16 separate dual axis accelerometers. This data acquisition system is used to measure and record acceleration data from wave propagations that are generated by the impact of a hammer on a striker plate and are modified by an inclusion or occlusion buried in the soil media. Thirty-four two-axis accelerometers were placed at surface and embedded locations on either side of various inclusions buried in the test pit. This large number of accelerometers permits experimentally obtaining high quality spatial and temporal data that can describe the character of the generated wave-forms and the modification of those wave-forms caused by the inclusion. A number of differing materials and geometric forms are used to create inclusions in order to provide sufficient data to permit ascertaining the ability of the measurements to describe the character of the inclusion. Continuous Wavelet Transforms are used to remove background noise and to aid interpretation of the character of the generated wave-form.
