AM Radio and Police speed cameras
« on: 06/02/2015 11:46:41 »
Just as I was done listening to the South African 702 Show, I drove past a temporary speed camera, the type where the cop has to man it.

The odd thing was, that while listening to 702, which is an AM radio station, I totally lost the signal for 2-3 seconds which seemed to be right where his camera was aiming.

So the question(s) is: what technology does that type of camera use to detect my speed (I've heard RADAR), and would it be possible for that to mess up an AM radio signal?

It's possible for a powerful radar signal to swamp bits of electronic equipment. I'm surprised that a doppler speed gun does it but there have been incidents of tractors being "hit" by fighter planes practicing locking on to slowmoving targets (not enough enemy tanks in Yorkshire, it seems), and I've had a mobile phone destroyed by the weather radar of an airliner.
