The most recent deaths of Marines by remote detonation of a I.E.D. got me thinking about what could prevent such an occurrence in the future. In posting this thread I hope to get people who know about such things to begin to think about this problem and talk to others who might be knowledgeable enough to get a solution identified and then get the resulting counter-measure device issued to our troops. I do not have any specific expertise in this field, but here are my thoughts.
As I understand the situation these I.E.D.’s are remotely triggered and are probably done so via a radio transmission. Would it be so difficult to develop a multi-frequency transmitter augmented by a PC that would rapidly broadcast a full spectrum of frequencies by a lead vehicle before a convoy passes by any given point on the ground. The point would be that the I.E.D. would be detonated before our troops are placed in harms way. No doubt there are some things I haven't thought of here, but does this idea make sense? Is it workable? Can we as a group move this idea along? Something needs to be done! :patriot

to be honest, i don't know why something like this isn't being done in the first place! i mean we are the US, and we have billions of dollars of weapons, why not some sort of preemptive defense, i am no pro, but it's not like these insurgents have the $$$ the US does, so i'm sure we can one up them on this :rolleyes

A lot of wounded and killed GI's would be healthy today if they had some armored humvees instead of the unarmored ones that the US sent over there.

Its not a situation that can be immediately remedied, but maybe we should have more armored humvees in general for the future.

Just read an article where some guy made a remote key fob that went through all the combinations in like 15 seconds - thereby able to unlock nearly any remote keyless entry car.

The problem is, however, quite difficult. We were experimenting a while ago with something like the key fob for garage doors - but newer garage doors actually work on a binary code - so you can't just transmit a signal on a frequency, you have to transmit a number, like 1001001011010, at a given frequency (of which there may be 16 - 32 different frequencies). And the number rotates (meaning it changes each transmission).

So if these IED's are simply using garage door opening technology, that may really complicate cracking codes and triggering IED's unintentionally.

Aren't our efforts to contact lifeforms on other planets ie. SETI (Search for Extraterrestrial Intelligence) based on broadcasting across many freqs. and using binary codes? After all we don't need to do anything but hit the trigger freq. to cause it to detonate. This approach may be way to simplistic though, and the fix is far more complicated, but if we can put a lander on Mars... how tough can it be? I can't believe the military can't give our troops the proper equipment to fight with. No wonder they have patrols that are balking at convoy escort orders.

Have read of devices being set off by using a cell phone as a triggering device. Probably easier to get your hands on a cell phone in Iraq than most other types of radio controlled, remote activated devices. Once armed, dial the number and boom! Almost impossible to pre-detonate in the way you describe.

The human mind is a wonderously inventive thing. When it is used towards a distructive goal, it can be frightening. The good guys have always tried to stay no more than one step behind the bad guys. Solve one problem, theft, terrorism, hackers and computer worms comes to mind, and the push is on to circumvent that solution.

wow, I was just going to post that if I were a terrorist (which I am NOT), I'd just use a digital cell phone with the detonator connected to the ringer - it's very unlikely that anyone would be able to get a cell phone to ring by chance, either by dialing randomly or through some broadcast signal.

Scary to think I can think this way... If only I could find a way to use my powers for good...:D

Instead of pre-detonating the bomb, maybe they could just keep it from going off. I had heard of a device that they have in Japan a couple of years ago that blocks all Cell phone calls. They use it in crowded places like movie theaters, because in Japan everyone has a cell phone, they use them constantly, and could never concieve of turning them off, so they made jamming devices to keep the peace in noise sensitive areas. I remember the article because I wanted one myself so bad!

If they had a device like this on every truck, hummer, car etc, at least the most common triggering device would prove useless and cut down the percentage of successful detonations. What the papers don't tell us so much is that hundreds of these IEDs are found and neutralised by our guys. I believe that most are not successful. It's just that every single night, organized squads come out and plant dozens of them. Only the successful ones that kill or wound a US GI get reported. It's a difficult problem, and unfortunately I believe that we need tens of thousands more troops there to go into these towns and find the storage and manufacturing sites and to watch the major highways more carefully. Hate to say it, but there ain't no cheap way out. :(

I can deal with the price in terms of dollars and cents, it's the price paid in wrecked and dead bodies I have a real problem with. No question, if it(device) uses a radio trigger it can be jammed. It just occurred to me that it would be really funny & productive if our guys figured out how to get to the people that make these things (IED's) just as they arm them. Boom! :cheers

Hummm

I think you are looking at it the wrong way. The media likes to make it look like some sophisticated attack but in reality is really simple. You just find a mortar or bomb that is laying around because you don’t have a way to shoot it. You dig a big whole in the road. Put the bomb in the road with the detonator end (part that makes it go bomb) at the top. Then you put a piece of scrap metal on top (old car doors work fine). Then cover it with dirt. When a car dives over the door it presses on the bomb and boom.

There really is not a need for all the electronics and remote triggers. Guerilla fighting works because it is so simple and easy to do. We can track down electronic signals in about 7 min to an area of about 20 feet but we can not find some guy with a shovel dragging a bomb around the desert. Osama uses a VHS camcorder and makes a video that is carried by some guy on a camel. If he was using satellite uplink equipment to send his message we would bunker bomb his cave in about 20 min.

The human body is very week. It is easy to kill just about anyone with anything if you catch them off guard.

As for Jaming...we do that and it is easy. The problem is that if we find a good way to stop it they could just use 200 ft of speaker wire.
