Oops didn't notice there was another page of discussion..with the article link already.
The last company I worked for (electronics design) had enquiries on building radar detector foolers. We got some 25GHz radar diodes and some 60GHz crystals, but it never went any further. Been thinking about building a simple speed camera if I ever get time...

Slightly off topic, but radar jammers are illegal here since the MED radio licensing scheme covers those frequencies, but laser jammers are not illegal as the laser (light) spectrum is not licensed. Otherwise your TV remote would require a licence. They could specifically legislate against them of course. Correct me if I'm wrong.

I would be keen to give a go at building one :)

Although I'm not sure what's worse at 3am, a speeding car with a sub, or a car slowing down with a sub...

Will only slow you down in the area once/twice.

Once you realise that there is a fake radar source you can drive as usual.

This could be the plan. Once a fake radar source is in a set place for a while and largely ignored by radar drivers, the police may set up a speed trap.

This was common with fixed speed cameras years ago. Some boxes were empty, with cameras being switched around at random.

what confuses me about police radar guns is how on earth can they verify which vehicle was speeding? the stationary speed cameras take a photo of the numberplate but do the handheld ones do that?

Except most decent detectors tell you how many radar sources there are.
If there is 1 its the fake source if there is 2 then take extra care.

Stupid waste of tax payers money once again.

Yeah stupid waste of $7000. Which in the scheme of things is nothing.

I actually think it's a good idea. For instance, would you like it if they put one outside your house?

Oxymoron. Different technology there.

Radar = in car, Stalker Dual (one in front, one in the rear) which have all sorts of smarts to work out which lane/car. (But no, no picture.. just guesswork. But unless you are REALLY innocent most people take it on the chin)

Handheld = LiDar = lasergun.
Has an alignment nib like a gunsight, or a screen they look through filters the wavelength and lets them see the dot hitting your car.

Have you noticed the hexagonal cuts in the road (one per lane) in the field of view of fixed speed cameras? They are coupled with an induction wire loop in the road. I'm not sure if they actually measure the speed with the loops, they might just detect which car was in that spot and use radar/laser to measure speed.
What concerns me is when I see those cuts in the road but didn't notice a speed camera...haven't been ticketed yet though.
The police have a little target they look through on the handheld ones, so they know which car it was. Would be handy for them if it took a picture too, but I doubt it.

SiliconChip mag / Jaycar had instructions / kit for speed radar which might be a place to start, rather than from scratch.
