摘要：

The acoustic-to-seismic coupling landmine detection system based on a parametric acoustic array was constructed to study the application method of the parametric acoustic array in acoustic landmine detection technology. Based on the theory of acoustic-to-seismic coupling landmine detection， the parametric acoustic array was used as an acoustic energy source to excite the surface vibration which can be detected by an accelerometer. The three-dimensional characteristic maps of surface vibration under different types of landmines and buried soil conditions were constructed. The experimental results show that the acoustic-to-seismic coupling efficiency of the soil above the landmine is obviously better than that of the bricks and other disturbances，and it is affected by the type of the landmine and the surrounding soil conditions，which indicates that the parametric acoustic array can be used for further research on the development of acoustic landmine detection engineering system. © 2022 Editorial Board of Jilin University.
