Eric,
Do you have a presentation you could share with us?
The question is, can you detect a police car's radio from a far enough
distance away so that you could slow down before they check your speed
with a Laser?
From what I have read, people seem to think the radio may be too well
shielded.
This for educational purposes, of course.
I was quickly going through the list and this one just happened to catch
my eye... there are a number of 'police RADAR' detectors
out on the market. There's no need to, execpt for 'educational'
purposes, created such a detector.
What 'passive RADAR' suggests to me is using the myrad of RF signals
which are emitted all the time, to then monitor and intripolate
the existence of objects which reflect these emissions.
Back in the ancient days be fore Cable TV, and TV channels were received
from the air by an antenna, the passing of an aircraft in the line
of signal for a TV channel would induce a distortion of the received
signal... it was very anoying... but that is the fundamental principle
of 'passive' RADAR. Such a distortion received at various locations
could then be used to locate the object which was moving through
the signal.
