Undetectable Radar
"The radar uses a very low-intensity signal across a wide range of frequencies, so a TV or radio tuned to any one frequency would interpret the radar signal as a very weak form of static."
http://news.yahoo.com/s/space/20060627/sc_space/newradarisundetectableinventorclaims I don't know what this means for those of us with radar detectors especially once the police start using this if this holds true.

It'll be a number of years before it hits the market, if it works out. Fossil fuels should be exhausted by then.

If it is "undetectable" than what use is it? Radar is just rebounded radio waves. And if you can't detect the rebound.....????

Exactly. It emits, it's detectable. Getting a reciever to be as frequency agile as the outbound sweep is the key.

Looks to me that someone is trying to reinvent the wheel. Ultrawideband (UWB) technology has been around for awhile but not picking up much speed in the standards area. See http://www.ultrawidebandplanet.com/ for more information.
Edit: I see that the inventor has some strong credentials in the field of radar and electromagnetic fields, so he may indeed have come up with a high-power version of UWB. Last edited by 914GT; 06-27-2006 at 11:25 AM.. |

The ultrawideband technology works because the signal is spread over a large group of frequencies. If some frequencies are covered with a signal, others can be used to recreate the missing data with algebraic coding techniques. This has been used already in long range wireless modems. Once several of these type wireless modems get turned on in the same area, the signal to noise ratio will suffer and the available bandwidth drops. I imagine the same is true of the other stuff. Once they start using it someone else will start producing a lower cost noise generator. Put these on several cars in an area and the system will have a lot more trouble. Should be pretty easy to come up with a bunch of low power transmitters, eh?
Oh, and don't do this because the FCC will likely take issue with it. Just pay your "High Speed Road Use Tax" and move along.........
