   There was a US project in the 1970's ('Musketeer'?)
   which supposedly studied ways to distinguish between
   different aircraft types using radar. One thing it
   was looking for was different engine characteristics.
   Counting the blades I don't really believe, but 
   doppler effect and vibrations maybe?

   There definitely is some work beeing done in this field,
   because it has been officially stated that the aircraft
   recognition libraries will not be shared between the
   four nations in the EFA programme.
