Assuming the F-22 is radar stealthy etc due to its shape and
materials,
is
it possible that you'd get a decent radar return from the radome?
After
all, the aircraft radar goes out through it, so whats to stop (a very
lucky!) ground or other airborne radar getting through it the other
way?
Or
are radomes made of mono directional materials?

A return is a reflection, since the radome is transparent to
radar you get no reflection and hence no return.

So would it be possible to get a return from within the radome, e.g. the
radar RxTx surface itself, or the bulkhead etc...


The radome is transparent at certain frequencies from what I've read.

Also, timing in the receiver should prevent that as well as variable
gain/distance. STC is what they called it in our old RCA sets.
Amazing how the terms main bang lockout and sensitivity time
control just popped into mind after 30 years. :-)
