Radar That Sees Through Walls Built In Garage

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.

Be careful making stuff cheap and easy.

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.
