  Quite the interesting piece on ECM, and quite informative.  Having
worked in ECM for a short while it is always interesting.  I think,
however, that even if the passive systems or those with electronic
modifications are expensive, there sure seems to be a market for it.
Perhaps it is the modern-age answer to the 'rich ignoring the rules'.
 
  Of such interest is the newest addition to the home ECM scene, the
aircraft detector.  It is essentially the same as the radar detector in
that it is an alert device, but it operates by monitoring the police
aircraft communication freqs and with some minor discriminator 
circuitry
is able to determine approximate distance and course.  The latter must, 
of
course, be relatively crude.  It then 'assesses' whether the aircraft
poses a threat to your speed jaunt.  It shouldn't take long before the
police alter the frequencies or go silent, but it is interesting the
amount of money people will pay to drive fast.
 
  At the ultimate end of sophistication would be --hypothetically
speaking, naturally-- a CW doppler jammer computed to return the 
correct
frequency to the radar to make it appear that you were really doing 55.
It would take a bit of integration with the car's electronics/speedo 
and
some interesting programming, but although it seems feasible I don't 
know
if it would really work as it should or just confuse the radar.  Maybe
just a big chaff gun on the front of the car?
