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."

I hate these pseudo-tech articles.

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.

Seeing inside a room is one thing, but realistically, the potential for invasion of privacy is much larger with the wiretap field.

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?
