The one good thing that Ultra2paranoid posts did was remind me about the development of the RADAR flashlight that cops may be carrying in the future. The things work by detecting the pattern of human respiration and gross movement of objects. There's several ways to combat something like this. We know that radar can't penetrate metal, and that foil can reflect radar (chaff). Soooo, hide behind (or in) metal objects like filing cabinets, ovens, things like that. Also, there's a material found at hardware stores called "Reflectix". It's an insulation material made of 2 layers of bubble wrap with an inner layer of aluminum foil, and 2 foil layers on both sides. At $2 per linear foot for the 4' wide material, you could spend $10 for a 5' x 4' sheet of superlight and flexible radar barrier. Just tape or wrap it between you and where the cops would be. As long as it's not moving, the cops detector won't know it's there, or you either. Another advantage of this material is that it can also be used to hide from thermal imagers. I'm working on that idea for my site. Another possibility would be to use a radar detector (car type) to detect if they're using a radar device. I don't know if it would work with this type of radar device because of the nature of the emissions, but if it does, you'll be able to detect the presence of the radar long before it can detect you, giving you time to hide. Also, you can use radar yourself in the form of an "electronic doberman", a motion activated electronic barking dog alarm ($100) that uses a radar system to detect motion (within 25') through walls. Remove the circuits from the casing and instead of being hooked up to the bark chip, connect it to a solenoid that triggers your weapon. Point it at a wall (aim for knee level) and when the cops legs move into the beam, the gun automatically fires, cutting them off at the knees (literally). The only problem with the dog alarm is that it can't tell the difference between an object moving in it's field of view, and it's field of view moving. So, to work, you have to keep the gun stationary, you can't sweep it to search for the cops like they can for you. You could leave the rigged gun behind, pointed at a door or such, and while your slipping out the back, they think your shooting at them. Wouldn't that be hilarious? Maybe leave a tape recording of someone (not you) ranting and screaming too? Could you imagine the looks on their faces when the finally busted in? HAHAHA! Missed me you dumb fucks! Of course, you could hook up the detector to set off a bomb when the cops move past it on the other side of the wall. Shit, if you stole these things from a store (I think Radio-Shit has them) you could have a bunch of them set on timers to randomly turn on and off. Sort of like the "houdini mines" from DS9. A hallway they walked through safely a dozen times all of a sudden becomes a death trap. And only when there's someone there, not like a time bomb that would most likely explode when no one was there. Decoys may be possible too. A coat hanger with a person sized length of aluminum foil hanging from it and attached to the ceiling by string would turn randomly from the air currents. Maybe a foil balloon attached to a small pump that rhythmically inflates and deflates to simulate a persons breathing? ------------------ |

I read somewhere that you can also use a survival "space blanket" against thermal imagers. These are the blankets that are silver and look like they are made from aluminum foil. |

I saw this one spy show, where a guy was a spy for MI6, and he was spying on KGB, he was a double agent, well, he found a note in his house, they were out to get him, by the way, he was the most inconciderate SOB there was, he left his wife and his daughter to escape the KGB. he went to his partners car and opened the trunk, opened the secret compartment behind the seats and wrapped himself in a space blanket and got inside, the spcae blanket was so they could not use radar or whatever. he got away and is still alove(well he was at the time the show was made) ------------------ "... always look on the positive side of things, blow things up not down" -- Ragnar Benson |

Unfortunately the space blanket isn't good for that sort of thing. That very idea has been discussed and shot down in usenet discussions. The problem is that the blanket isn't as efficent as advertised at reflecting back the heat. Plus it has zero insulative value, and is very fragile, basically aluminized cellophane. The reflectix material has 2 (not 3, my mistake)aluminum foil layers with 2 insulating bubble wrap layers. It has something like an R-18+ rating. And it's quite durable. There's a website that sells camoflaged bags that purport to defeat themal imagers. www.stealthbag.com . I saw the pictures of it in a magazine (I think American Survival Guide) and a close-up showed the texture of the bag. It had the same texture as the reflectix! Since I haven't seen it in person, I can't say that it's made from reflectix for sure, but it sure seems possible. ------------------ |

I've seen that shit in hardware stores, i think its in the pipe section(gee, why would I bee in there? )I was thiking about getting some, but I changed my mind, it is really thick... ------------------ "... always look on the positive side of things, blow things up not down" -- Ragnar Benson |

It's not THAT thick. Plus, it weighs next to nothing, and the insulative value of the bubble wrap greatly increases it effectivness in preventing IR detection. ------------------ |

Why not make a radar jammer? ![]() Sure they would know someone was out there jamming their equipment, but they wouldnt know where. Then all of a sudden "pop" "pop", and one by one they start falling down. |

Lol that reminds me of a time a few years back when I made a certain device that was capable of severely disrupting radio communications up to a range of a few thousand feet. ( guessing ) I am guessing this because thats how high that airplane was when I disrupted it's contact with ground control hee ![]() My friend had a portable cb radio and he tuned it into various bands, from police to military to public airplane transports. I stopped the device after a few minutes because of the inherent danger to all on board that plane... no communications with ground control, just a shit load of garbage and static coming over the speaker Think of the applications this could have in a cop chase... they bring in choppers and squad cars.... as long as you can shake off the ground units and keep the device going when you are leading the helicopter into a ambush your more or less home free because the chopper can't radio your current position or heading to anyone hee |

I actually discovered that jamming property by accident :/ It first rose to my attention after I switched it on near a television set and the picture just went to static. There are also limitations to the device. |

this sounds great, could you ppost the plans? ------------------ "Tick, tick, tick, tick ...Haa! That fucking shotgun is straight out of Doom" -Eric harris |

Unfortunately the radar flashlight uses spread spectrum for it's emissions, so a jammer won't work for that. Besides which, if you use a jammer, your going to jam your own detector, blinding yourself to the cops scanning. Better to passively monitor their progress and hide stealthfully. Then they'll believe their machine when it tells them no ones there. People tend to get sloppy when they let a machine do the work for them. If it's jammed, they'll have to manually search every nook and cranny. ------------------ |
