New Radar Sees Through Walls

artemis67 writes "A small Israeli company has developed a radar system that uses ultra-wideband technology to produce three-dimensional pictures of the space behind a wall from a distance of up to 20 meters. The pictures, which reportedly resemble those produced by ultrasound, are relatively high-resolution and are produced in real time. Wow, it sounds like the potential benefits of this device are huge, saving lives of soldiers, firemen, or police; the potential for privacy invasion, however, is similarly large."

The display doesn't give you Superman see-everything-in-detail-through-walls kind of powers (Lois Lane: "what kind of underwear am I wearing?"), but it's still pretty cool that this kind of thing can be done without using heat signatures and whatnot.

      Actually, I think a low-resolution system is a worse invasion of privacy than a high-resolution.

      A low-resolution system is liable to lead to much more subjective interperetation in court. So you see the shape of the blob change slightly while he's at his computer. Is he drinking coffee or is he getting off looking at child porn?

      That's why we have that whole "beyond a reasonable doubt" burden of proof thing.

      If they have a low-res recording of you building a bomb, your defense attorney can reasonably argue that the blob the jury sees could be doing anything. I doubt such images would ever even be considered admissible by the courts if they were of such low quality.

      The reasonable doubt provision does not aim to provide "perfect justice". Perfect justice would be if everyone who committed a crime was convicted and everyone who was accused of a crime he or she did not commit was acquitted.

      Fortunately, the authors of the US Constitution believed, as I do, that it's "good enough" to let some people who commit crimes get acquitted if the government can't prove beyond a reasonable doubt that they're guilty, to ensure that not a single innocent person is convicted.

      The real problem is that our law schools produce people who can, as Socrates was accused of doing, make the weaker argument appear to be the stronger, and convince juries to convict people who not only aren't guilty beyond any reasonable doubt, but who are later proven beyond any doubt whatsoever to be not guilty when new evidence or new techniques of analyzing evidence are used. Just having one person on death row exonerated by DNA evidence shows that the system is horribly broken.

      Of course, the sort of "strict constructionists" who believe that the government should never, ever, even think of overstepping the authority granted to it in the Constitution are, ironically, the exact same people who think it's a "technicality" when an alleged criminal is set free because the Constitution includes specific provisions to protect the People from abuse by the government.

You can *trust* the government these days -- it's not like our leaders are so untrustworthy anymore that they might get a blowjob or two. That's why you won't be needing those pesky rights to free speech or due process anymore.

    Seriously, this sort of thing might be great for our soldiers in the field, and in my little optimistic heart I'd really like to think that something like this could exist in our country without being abused by the "Total Law Enforcement" crowd. I mean, the US *should* be able to operate that way, what with having Constitutional protections and all that.

    Given what's been going on recently, however, it seems like only a matter of time before somebody justifies using it on Americans on the grounds of terrorism prevention (after which, of course, everything will become terrorism of one kind or another). I mean, the USA is suddenly in the business of above-the-law prison camps, war without end and other awful little things like abusing the prisoner (in a non-masterbatory context), and all it took to get us to this point was the deaths of 3000 Americans.

    Its been a while since I've done any RF, but theres some things in that article that are a little bit, odd, to say the least.

    Camero developed a certain kind of ultra radio wave that can be emitted to generate a high-definition image and also invented the technology that allows the enhanced wave to pass through virtually any wall.

    How exactly does one develop a "certain kind of ultra wadio wave", and how does one "allow it to pass through any wall". Perhaps they have a valid technology, but the person who translated this to layman's terms should be shot for creating a document that makes it sound like the company is selling smoke and mirrors.

    Actually, the part of the article that I found most interesting was

    ...an Israeli security source told WND that Israel recently developed proprietary technology that can discreetly put an electronic field around a building or area that gives users the ability to monitor and control every electronic emission within that field, from electronic can openers to fax machines, computers and cell phones.

    It seems odd to me that the same people who can follow that the DMCA is problematic because it bans the tools not the abuses of the tools can't make the connection when its non-computing related.

    Peering through neighbours walls (with this technology or drilling peepholes) is the offence. Would you argue that drills should be regulated because they could be used this way ?

    If anything the main reason to regulate it is likely to be because long exposures to low levels of radio frequency radiation seems to do bad things to human beings so operating one might require training, care and exposure limits.

    I'd also disagree its just a military tool. It has clear civilian usages including earthquake searches (because it can visualise spaces not just people so gives more info) and even boring stuff like inspecting buildings. Having had a large hole hacked in my house to see if a crack was structural I can certainly appreciate the civilian value of having tools to inspect it effectively without the mess, and the dust, and the redecorating.
