Seismic wave estimation for buried target detection

We introduce an algorithm for buried target detection in the presence of induced seismic waves. Ground fluctuations are measured with an array of laser Doppler vibrometers (LDVs) to estimate the presence of buried objects. Buried targets cause scattering of the subsurface waves, resulting in anomalies in LDV measurements. The seismic wave response depends upon many factors that are rarely known in advance, and drastically affects features used for target classification. We introduce a statistical method that identifies the travelling wave, and anomalies in its propagation. Using standard pattern recognition methods, the proposed algorithm is shown to improve target detection performance over the raw data.
