Our Worst Nightmare?

[swarga]

Suppose someone was to develop a FHSS RADAR gun. Frequency Hopping Spread Spectrum radios only transmit on a particular frequency for a few milliseconds, then switch to a new frequency in a pseudo-random hopping pattern. It would be like Quick Trigger on steroids!

Even if you know that FHSS was in use, and even if you also know the hopping pattern, FHSS RADAR would be almost impossible to detect. A cop could leave this sucker blasting constantly and never trigger any current RADAR detector.

The good news: this is an old idea, and had been around for almost 2 decades. The fact that such a thing does not already exist means it's either too difficult or too expensive to build and/or get licensed. Or perhaps no one bothers because LIDAR does a much better job.

Not a nightmare at all...


For some reason my CB doesn't care what frequency the LEO's are using, or if they are running radar/laser at all...




The newer and more sophisticated their technology gets... the more I will rely on the old stuff.



As southerners might say "Dat right der ain't hap-nin' bwoooyy"... we won't seen it forever and then some...

I think Stalker made a version of the ATR that frequency hopped 34.2~35.2 GHZ. Don't think it was ever used in the States though.

I wonder why it was dropped?

As they say "seek (in this case search ) and you will find". I think this explains it..........

Well, somewhat. Even The Professor doesn't know what became of this idea. Is it truly dead, or simply being refined in a research lab somewhere? Perhaps it has simply been waiting for the cost of certain components or technologies to come down enough to make such a gun cost-effective?

If nothing else, I wish the dickheads who make adaptive cruise controls for passenger cars would use FHSS RADAR so as not to generate false alarms on my RADAR detectors.

I think even if such gun came out today it wouldn't take long before all the detector companies or someone got their hands on one and reverse engineered it. Eventually leading to a way to crack its code or completely jam it. Maybe the gun could never see the light of day because some workers were also RD users and thought about protecting everyone from being completely spied on. Who knows...

Yeah I don't know what became of it, not sure if the FCC denied them approval etc. There were a couple of articles on it back around '92 that talked about Stalker seeking FCC approval for a spread spectrum unit. One of the articles said that Whistler had filed an objection claiming that it could interfere with the future development of vehicular radar systems. I asked Michael B about that once, and he didn't know anything about it...

I saw it listed here back when I was digging up info on the Stinger DSI. I thought perhaps it was a gun that Stalker marketed/sold in Australia. I don't see it or any other ATR listed on the Stalker web site now..........US or International.......so I assume if they ever did, it's a dead animal now. Thank goodness.

How police radar is used and associated problems and errors.

While the US military was the first to develop it, "our" former corporation, CMI, wrote the book on consumer digital spread spectrum technology which is now used in almost every cordless telephone available. Before CMI went belly up, our last phone model had a 1 mile range The cost of developing and producing this technology along with cellular packet data modems was key to why CMI went under. The tech was way ahead of it's time, the cost was greater than the market could bear.

We still have some of the talent from then so I'm sure we could come up with a solution should this threat ever surface.
