Optimal Experiments With Seismic Sensors [PDF]
2006 IEEE International Conference on Acoustics Speed and Signal Processing Proceedings, 2006 In this paper, we consider the problem of detecting and locating buried land mines and subsurface objects by using seismic waves. We demonstrate an adaptive seismic system that maneuvers an array of receivers, according to an optimal positioning algorithm based on the theory of optimal experiments, to minimize the number of distinct measurements to ...
