Radar That Sees Through Walls Built In Garage

Posted by Soulskill on from the real-life-wall-hacks dept.

szczys writes: Building radar in his garage is nothing new to Greg Charvat. He has a PhD in this stuff and has literally written the book (and a University course) on building your own radar system. This time around it's Phased-Array Radar. This is more than just judging the speed of a baseball or Ferrari. This rig can actually see through walls. Greg uses the example of a soda can to illustrate the quality and resolution possible from this type of system.

    I think the writer is saying on average people are more likely to build with plywood or drywall in their garage instead of less permissive materials like brick, concrete, or metal.

    So, statistically speaking, a radar system is more effective against walls built in a garage than walls built outside of a garage.

    As usual, the article may provide clarification, but I've found I can avoid the trouble of reading them by simply making wild assumptions.

    Can it also see through walls that were not built in a garage?

    In KYLLO v. UNITED STATES , the Supreme Court held in 2001 that:

    Where, as here, the Government uses a device that is not in general public use, to explore details of the home that would previously have been unknowable without physical intrusion, the surveillance is a "search" and is presumptively unreasonable without a warrant.

    in determining that use of a thermal imaging device whose output was used to establish cause for a search warrant was, itself, a search that required a warrant.

    By making intrusive surveillance devices available inexpensively (perhaps by showing hobbyists how to build their own), such devices could move (as planes have) into "general public use" and then be usable by police without a warrant to surveil areas normally off-limits to them without a warrant.

    Why is there an "insightful" mod and why isn't it "-1"? If I wanted insight, I wouldn't be reading /.
