Radar used to detect concealed weapons in public spaces


Radar used to detect concealed weapons in public spaces

An electrical engineering professor at the University of Michigan believes that a type of radar, part developed by the Department of Defense, has the potential to be used as a means of detecting concealed weapons. Originally intended for military use, it is possible that the millimeter-wave radar system could be used to detect weapons across distances as large as a football field.

Professor Kamal Sarabandi was watching the aftermath of the Newtown shooting in Connecticut when he was hit by the notion that his work for the military may have a use a little closer to home.

The technology that he developed is currently being used in a number of applications, including collision avoidance systems in cars and in military targeting systems. The radar itself isn’t particularly unique, but Sarabandi’s pairing of the tech with Doppler radar signal processing allows it to pick out an individual in a crowd using a technique called polarimetry.

    big brother is getting closer. once they know i have it they better not try and take it.

  • gailfilerino0403

    Believe me they will use that on the law abiding citizens.

    • Alexander Davidson

      That is an understatement! – but what about the CANCER risks that are ADDED into everyone’s lives by AIMING radar at PEOPLE not metal objects?

      • Constitution101

        That could be an avenue to attack this issue with… the health risks of radiation. I’m sure Teachers don’t want any more exposure than we do. Remember the X-ray machines TSA was using? That got removed.

        I don’t think the slobbering left-o-crats give a rat’s posterior if the radar affects anybody. It’s all about “keeping our children safe”… (insert puking noises here)

    Laws to the left doesn’t mean anything to them, they are your gods, your propaganda media, little hitler worshippers who can’t get their heads out of where the sun doesn’t shine.

  • Russell Coleman

    Haven’t there been cases of Millimeter Wave Radar having been harmful to people with Pacemakers and personnal defibulators?

    • Alexander Davidson

      Ahhh….. THAT…. wherever there are such problems, there will be excuses made by the operator’s cleverly spoken scientists, which the average Joe Blow hasn’t got the funds to challenge! What would happen if victims decided to “take out” such heads of operations en masse? – Would that change anything? – not if there is a massive amount of loot to be made by keeping system on targeting the 1/1000 persons that they see as risks, of which 1/10000 may be actual risks.

    Is that against your Privacy ?

  • act

    It is already in place in many locations.

  • Stephen N Russell

    Use this at airports & reduce the TSA hand search games alone with dogs & sensors, nationwide
    Use low beam radar for effect alone

  • KDS

    I hope those guns are firing at the time they come to collect our weapons.

  • Berzrkr50

    Seems to me that it would be easy to get around something like this. Why not wear a vest coated with the same substance over your upper body (over your pistol) to get the same reflection that they’d get with just your skin? As with any security scheme, there’s ALWAYS a way around it if you use your head for something other than a hat-rack…

    • $5708171

      Oh my. Where then shall I place my hat??

  • B.f. Caffrey

    Seems it is time to start marketing metal cases for iPhones, pagers, wallets that contain metal and even “pocket liners” that are made from metal to thwart these machines. At least until they try to refine it to show an image of the reflecting object. Meanwhile, I wonder if holster makers will incorporate radar-absorbing materials in their products?

  • watchdogman

    guess they will then know I am carrying a legal concealed weapon…No big deal!

  • James Maxwell

    Considering that RADAR acts much the same as MicroWave ovens do how will that effect the health
    of those subjected to its usage? Probably cook us from the inside out and leave lasting birth defects
    on the unborn. Of course for the dimless that not a problem as they support killing babies on a
    massive scale thru their abortion clinics such as planned genocide.

  • Bobbi Sue Myles

    This is one of the most egregious invasion’s of personal privacy possible. This guy is not thinking with his right brain. must have his brain relocated to his ass as do all who work for military invasive processes.
