Defeating tunnels across the border
quote:
The Engineer Research and Development Center developed the border tunneling activity detection system-point, or BTADS-P. It includes an array of buried geophones that listen for construction activities.
?This one is very infrastructure rich,? Perren said. ?It?s somewhat more expensive to [deploy] but it?s very good at finding localizations.? It can tell operators where the underground activity is taking place, and they can adjust the depth of the array as they conduct their search, he noted.
The Homeland Security S&T directorate paid for part of a system that was installed near San Diego, Kaczmarek said.
ERDC has also developed a less expensive linear sensing system that uses a buried line of fiber-optic cable to monitor and process acoustic and seismic energy associated with tunnel activity.
These passive detection technologies work very well if the adversary is in the act of building the tunnel. But if the tunnel already exists other types of capabilities are needed to detect them, Perren noted.
One such technology is the active seismic imager, or ASI, which is a modified Toolcat. ?Essentially we have a Bobcat with a thumper,? Perren explained. ?It pounds the ground and we have a stream of geophones behind it that listens for that sound to propagate through. ? When there?s a hole in the ground the velocity structure changes and we can find that.?
Another capability is the electromagnetic induction system, or EIS. Using power and light wires, communication wires and transmitter-receivers it detects buried infrastructure that conducts electricity. It is man-portable and weighs about 30 pounds, according to ERDC officials.
Ground resistivity is a major area of interest. ?We put electricity in the ground using electrodes,? Perren said. ?When there?s a void it resists electricity. The electricity goes around it and that allows us to map its location.?
ERDC is trying to make the data gleaned from these systems understandable to non-experts, he noted.
?We?ve developed processing routines that take that huge amount of strange-looking data ? squiggled lines, this and that ? and turns it into something that is more likely to be usable by a commander? such as color-coded maps, he added.
Looking beyond ground-based systems, officials are exploring the use of drones to detect tunnels from the air.
Engineers at the MIT Lincoln Laboratory have been working on a new technology for JIDO. It includes an Airborg 10K unmanned aerial system developed by Top Flight Technologies. The platform carries an antenna and electronics payload and weighs about 15 pounds, said Christian Austin, an engineer with the lab.
If the UAS is surveying an area and it detects a large change in the magnetic field, that indicates there is something subsurface, he explained.
?It would fly around in circles and it would generate sort of a heat map of what?s in the area ? what you?re seeing below the ground ? or maybe it would fly lawnmower tracks [and] the output of the system would be some sort of heat map from the algorithm,? he said. A commander could then decide what action to take against any suspected tunnels.
The experimental system is currently in the demonstration phase, Austin said.
Officials emphasized that there?s no silver bullet technology for dealing with the tunnel challenge.
?There?s lots of different subsets to this that we?re going after,? Perren said. ?This problem set is huge, so there isn?t going to be one solution. ... We have to advance them all.?
Many of these systems have already been deployed in the United States and overseas for use by Customs and Border Protection and the U.S. military. The Engineer Research and Development Center is working with JIDO to improve their capabilities and decrease their limitations, Perren said.
?There are geologic differences between the Korean Peninsula, the things in the Middle East, the things in Afghanistan. So we?re looking at that and trying to incorporate how that affects the technologies,? he added.

Why not use what we have learned fighting Islam.

and once the detection systems are up and running at least in unpopulated areas detected tunnels could be destroyed by helicopter mounted deep burrowing missles packing high explosives........ 0 -

Use what they learned in Combat, I like it.0 -
Call the IDF
They know tunnels.

Find a tunnel and shove a fire hose down it and flush.

Better yet, get a few Septic system removal trucks, and let the Sheeit fly. Win/win. [:D]0 -
Let the honey dippers fill it with the good stuff. 0 -
"tunnels could be destroyed by helicopter mounted deep burrowing missles packing high explosives........"
Cheaper and easier to just run 200 gallon of propane into the tunnel and drop in a road flare.0 -
some creative ideas ...and what is the chance of this positive action being used against govt declared (special) people ??? 0 -
Maybe they can just breed up some really big ferrets. 0 -
