{Stus-List} The best Radar Reflector

Thus the B-2 is more an "absorber" than a "misdirector".
To relate this back to boats - our boats are pretty good stealth craft
in any kind of weather. Big ship watch officers don't want to look at a
screen full of noise and sea clutter, so they turn the clutter control
up and the gain down so that other big steel ships stand out and we
disappear. Also they like to run S-band radar because it penetrates
weather much better than X band. Bad side of that is the radar reflector
that would work worth a crap on S band would be huge :(

	And how long does it take a smart adversary to figure that one
out...I guess new systems don't work exactly that way for a reason and
radar absorbing materials received more attention from the defence
research community

	Radar sends out an electronic pulse.  When it bounces directly
back at the source, it is received and the time it took it to travel out
and back is computed into the distance the object is from the source.
As Joe has pointed out, early stealth technology, like the F-117, had
many faceted surfaces which did not bounce the pulse back to the sender,
but rather bounced it off in another direction.  Like throwing a ball at
an angled wall, it will not bounce back to you.  With no signal
returning, nothing appears on the radar screen.  If most of the pulse is
deflected and only a little bit returns to the sender, then the blip on
the radar screen will be very much smaller than what you would expect
from a war plane and might be interpreted as a flock of birds or even
random radar "clutter".

	Wouldn't that be a good way to get detected...how is that
function stealthy?

	FYI the original stealth airplane, the F-117, did not use the
"absorb radar" system to be invisible. What it did was do a good job
reflecting the radar another way than back from whence it came. It is a
flying radar deflector.
