New Technology For Landmine Detection

By

In Colombia, large areas are teeming with landmines that are almost impossible to detect with traditional methods. In collaboration with partners from South America, engineers at the German Ruhr-Universität Bochum and Technical University Ilmenau are developing a new mine clearance technology, based on ground penetrating radar. In the long run, they are aiming at creating a handheld device that will detect different mine types on rough terrain without fail and which can be used in the same way as metal detectors.

In Colombia, large areas are teeming with mines. Finding them using traditional technologies is as good as impossible, because all landmines are different.

In collaboration with partners from South America, engineers at the Ruhr-Universität Bochum and Technical University Ilmenau are developing an advanced method for humanitarian mine clearance in Colombia, which is based on ground penetrating radar technology. In the long run, they are aiming at developing a handheld device that will detect different mine types on rough terrain without fail.

Landmines almost impossible to detect with traditional methods

Even though Colombia has not experienced any military conflicts, many areas are teeming with land mines which had been laid by guerrilla forces and members of drug cartels. Because the booby traps were not industrially manufactured but had been assembled from various everyday objects, they are almost impossible to detect with traditional methods.

In the first step, the international research team built a number of land mines from everyday items, with empty detonators instead of explosives. They were used as templates for virtual computer models, which the engineers used to simulate the radar signal that each mine would generate.

Simulation of radar signals

The engineers analyzed the simulated radar signals to identify properties that are typical for mines, but are not generated by other objects, such as stones or shrapnel. This information is fed into the analysis of the gathered radar data; this is how they set up their system to perform an automated search for properties that are typical for mines.

In theory, the method works. Now, the engineers have to get it up and running in reality and optimize it for application in a handheld device. According to their estimates, it will take another two to three years for a prototype to be completed.

Mine clearance in Colombia agreed upon

In 2015, the FARC guerrilla and the Colombian government agreed on a comprehensive mine clearance. To date, the country’s military has been mainly using metal detectors to search for booby traps. However, the traps contain barely any metal, and there are many other metal objects in the ground.

“Only one in 2,000 found objects is a mine,” said Dr Christoph Baer from the Institute of Electronic Circuits in Bochum, who collaborates with Jan Barowski and Jochen Jebramcik from the Institute of Microwave Systems at the Ruhr-Universität. This renders the search extremely difficult.

Baer added, “All mines must be found, because it is a humanitarian project,” adding this is why the team knows that they won’t file any patents. The technology they develop is meant to be publicly available.

The Ruhr-Universität’s science magazine Rubin has published a detailed report on the project.

    robots. Use robots. Little, inexpensive to build ones. Take a truck load or helicopter load of them to an area that you want to be cleared of land mines, and let them walk over the area with a little “pounder” that stamps down as they spread out according to an algorithm that can be sure to get all the mines that might be there. So they blow up. That’s the whole point. DETONATE THE MINES in situ with robots…In fact, building the robots can employ many local residents, and make wealthy the producer. Seems like a no-brainer to me. (I was going to suggest releasing kangaroos, but animal activists might object. I know of no “protect the robot activists” as of yet.)
