摘要

研究了用于非金属地雷探测的声-地震耦合识别方法。介绍了基于声-地震耦合的声共振探雷技术的基本原理，讨论了如何利用声学参量表征地雷的机械特征以及综合利用声波共振和反共振的作用。设计了车载式声波探雷实验系统，测量了埋藏地雷时的地表振动速度。最后，根据扫描探测结果，研究了地雷的声学振动特征。结果显示：埋藏有地雷的位置会呈现振动特征的明显凸起，在给定实验条件下，地雷中心振动强度是无雷区域的15倍，利用提高信噪比的方法还可使该值提高到20倍。实验表明：基于地雷振动强度和扫描探测的方法可研究地雷掩埋位置的振动特征，而且所设计的实验系统具有操作简便、成本较低的优点。

Abstract

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.
