电磁感应探雷技术电子感应法仅能探测含有金属零件的地雷。采用电子感应原理的探雷器采用两个线圈。第一个线圈中有电流通过,产生随时间变化的磁场。地雷的金属零件在这个磁场感应的涡流中产生副磁场。用第二个线圈探测该副磁场。即可确定地雷的存在。而目前单兵手持和车载探雷器往往使用电磁感应原理。加拿大施莱伯公司正在研制的“松博”系统,以手持AN-192型探测器技术为基础,采用一个包含多个线圈的线阵,并将线圈装在底座上,确保在各种地形上均保持与地面的接触,从而能发现包含金属较少的地雷。该系统能以10千米/时的速度作业,扫描2～6米宽的范围。
Electromagnetic induction mine detection technology Electronic induction method can only detect mines containing metal parts. The detector with electronic induction uses two coils. The first coil has a current passing through it, producing a time-varying magnetic field. The metal parts of mines generate secondary magnetic fields in this magnetic field-induced eddy current. The secondary coil is used to detect the secondary magnetic field. The presence of landmines can be determined. At present, single-armed handheld and vehicle-mounted mine detectors often use the principle of electromagnetic induction. The “Sonbo” system being developed by the Canadian company Schlepper, based on the handheld AN-192 detector technology, uses a linear array of multiple coils and mounts the coils on the base to ensure that it is on various terrains. Keep contact with the ground so that mines containing less metal can be found. The system can operate at a speed of 10 km/h and scan a range of 2 to 6 meters wide.
