re radar detector detectors in article pslckinnmn matt ksu ksu edu nhowland matt ksu ksu edu neal patrick howland writes from what i understand about radar dectectors all they are is a passive device much like the radio in your car they work as an antenna picking up that radar signals that the radar gun sends out therefore there would be no way of detecting a radar detector any more than there would be of detecting whether some one had a radio in their car from my rather rusty knowledge of radio most radio receivers use a superhet circuit so that the incoming signal is mixed with a local oscillator giving a fixed intermediate frequency if that is more easily amplified the detector detectors work by picking up if re radiated from your radar detector in britain where one has used to pay for a tv licence there are were tv detector vans prowling the streets looking for people who hadn t paid their licence fee they had a couple of long solenoid antennae on the roof and i believe could triangulate an operating tv from the if i wonder how much of the if is radiated back from the detector antenna and how much from the rest of the module it might be worth putting the detector in a proper rf shielded enclosure andrew daviel vancouver canada advax triumf ca finger advax reg triumf ca for pgp key
