Abstract

The development of techniques for inspection of explosives and other hazardous materials has become more and more attractive as concerns about public security have increased considerably in the past years 1–3. Among all explosive devices, landmine is the most demanding target to be detected. Landmines were widely used in all kinds of battlefields and they are very difficult to eliminate once a conflict ends. The remaining landmines represent an enormous danger for the people, both military and civilian, that occupy the terrain affected by the presence of landmines. As of today, more than 100 million mines remain active and undetected in many fields around the world. Those mines claim more than 30,000 lives or injures each year. Although antilandmine technologies already exist and are being used in minefields, most of these technologies tend to give high false-positive results due to the presence of other objects present in the area.
