[aprssig] Vehicle Signatures

[Brian Webster]

What about the license plate scanning technology? Scan the plates and/or see
if the software will also recognize name and model badges on the cars or
even use image recognition software. At a fixed camera angle that should
work well. Ever upload a bunch of pictures to Picasa or Facebook and have
the software give you the option to tag one name to a bunch of pictures it
already recognizes as the same person in multiple images? IP enabled cameras
are cheap these days, you could still scan for RFI with a time stamp and
match the RFI capture with the image time stamp and maybe start to build of
an RFI signature database that way.

Thank You,
Brian N2KGC

Crazy idea for sure...  BUT  I'm thinkin' you wouldn't need a road sensor
with the kind of garbage they must be spewing.  KW of PWM.

A motor I designed was a 350 W (1/2 HP) DC Brishless and without any line
filter it destroyed any AM radio reception around. Of course if these cars
have an AM radio they must be doing some RFI stuff....
  So it'll take some measuring.  The Volt owner would certainly be willing
to investigate this - he's a ham. 

Bob, '
  Do you (can you) run HF in your Prius?
