Ok, I know this has the possibility to devolve into "Who's burried in Grant's tomb?", but it is a serious question.
First, let me say that I am an electrical engineer, and I am into ham radio and scanning. So my question isn't as silly as it sounds.
I know that speed measurement radar measures pulses of radio waves at various frequencies.
Do radar detectors simply detect a signal/energy at a specific frequency band? Or do they look for specific patterns within a signal (e.g. pulse rates, etc)?
Would a simple signal at 34.7GHz trigger a radar detector? Or would the signal need to be 'pulsed' as it is in a radar device?
