These guys need to find a science reporter who knows what a radio wave is.
(Note for non-technical types: "Radio waves" and "radar waves" are overlapping portions of the electromagnetic spectrum, with no clear demarcations between them.)
Radar chips are a really cool innovation. They will make possible a whole new generation of portable sensors, and they may turn out to be superior to conventional radio technology for some purposes. However, they aren't going to magically make radio spectrum bandwidth limitations vanish. The method the article describes for setting up "undetectable" radio communication with them also does not appear viable - it should be perfectly feasible to build a receiver that will pick up the transmission.
