Engineers at Ohio State University have filed a patent for a new "super radar" with multiple applications including police traffic radar. The radar is reported to be undetectable because it uses a generated noise signal spread over several gigihertz (GHz). Commercially available and fast digital shift registers allow pseudorandom waveforms (generated noise) to correlate the transmit and receive signals (noise). The inventors claim the system can be built for about $100.

Don't hold your breath waiting for this system to become available. There are many other and more mature technologies that would work (better). Research and development cost to perfect the new super radar is probably grossly underestimated, as is final production cost.
