Abstract:

Working with NVESD CM and ERDC, CoVar was funded to conduct data analysis and algorithm development for the detection of explosive buried threats in surface vibrational data. For this effort, CoVar was tasked with using available simulated and field data in order to better understand the phenomenology of detecting buried explosive hazards using measurements of ground vibrations. Historically, we have investigated a laser Doppler vibrometer LDV which measures only the component of motion of the ground along the line of sight to the sensor. New sensors are currently under development which may be able to sense all three components of motion of the ground surface at standoff. Using all three components of motion presents a much richer representation of the soil motion which can be used to detect anomalies and therefore buried threats. Much of how to utilize three component data is still unknown, as there is currently very limited data of ground motion over buried hazards.
