An acoustic-to-seismic coupling based discrimination method was investigated for experimental research of buried non-metallic mine detection. The fundamental theory of acoustic resonance technique for mine detection based on acoustic-to-seismic coupling was introduced. The acoustic parameters that characterize the mechanical features of buried mines were studied and the application of combination effect of acoustic resonance and anti-resonance was discussed. A vehicular experimental system for acoustic mine detection was designed to measure the surface vibration velocities with/without mines in soil. Finally, the acoustic vibration characters of buried mines were analyzed according to the results of scanning detection. The results show that the location with mines buried will exhibit an obvious boost in vibration. Under the given circumstance, the intensity of vibration in the center of mine is 15 times that of off-mine location. The intensity will rise to 20 times if the signal-to-noise ratio is increased. The proposed method can be used to study the acoustic vibration characters of mines buried location. The designed experimental system is cost efficient and easy to operate.
