blasted a hole in the clouds.
yes and no. the radar beam itself is basically the same as it was when it was originally pioneered in the 1930s. the equipment used to catch that
beam, analyze it, and send it to air traffic systems is quite different though. these days the computers in the systems actually weed out things like
weather, flocks of geese, and other objects that can interfere with the return, and in the case of the weather, puts it on a different channel that we
can display on our scopes to give pilots a real time version of what is out there.
of course there are also doppler radar domes on all major airports as well. i'm not as familiar with doppler, but i understand that it is quite
different from ours as it is designed specifically to look at the weather that is out there.....and when i say weather here, i really mean
precipitation. rain, snow, etc is what is really causing the echos....the beams dont really see the clouds.
and of course you have the radar units in the aircraft. much smaller and less powerful, but they still probe the atmosphere.
sorry so long winded, but to sum up, the radar waves themselves havent really changed, but the
amount of radar waves out there has increased
exponentially over the years (especially in large terminal environments like ohare), and
that might make quite a bit of difference....if you
believe in the alien craft theory that is.
