摘　　要：构建了基于声参量阵的声-地震耦合探雷测试系统,研究了声参量阵在声波探雷技术中的应用方法。在论述声-地震耦合探雷理论的基础上,利用声参量阵作为声波能量源激励地表土壤振动,利用加速度计进行地表振动的检测,构建了地表振动在不同类型地雷和埋藏土壤条件下的三维特征图。实验结果显示,地雷上方土壤的声-地震耦合效率明显优于砖块等干扰物,并且受埋设地雷类型及周围土壤条件的影响,表明声参量阵可用于声波探雷工程系统的进一步研究。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.
