A review of applying the non-destructive testing methods for detection of landmines

N Karimian 

There are several countries in the world that are still suffering from the presence of buried anti-personnel landmines (APL) and explosives located mainly at their borders. Since such types of explosives and landmines have an unlimited

lifetime, they could still cause deaths, loss of body parts or serious injuries to the genitals and abdomen of victims, even for decades after a war. Therefore, there is a growing need for accurate inspection and detection of landmines. There are currently several detection techniques, where each technique is suitable for a particular condition in terms of types of landmines under consideration, explosive materials, characteristic of the soil and objects buried, etc. These techniques all have qualities that make them suitable; however, they also suffer from shortcomings and technical problems, such as high false alarm rates, insufficient detection probability and generally very small clearance rates of mine fields, which results in many restricted areas for a long time. This paper focuses on providing a review and description of the currently existing state-of-the-art techniques for landmine detection. Moreover, it also provides merits and challenges attached to each technique, including the comparison of parameters such as complexity, false alarm rate and effect of environmental conditions.
