no... because you are sending a coded reply to a specific interrogation.

Would the MTI also filter you out if you had a Mode C transponder?

Reflectivity is not the problem. We conducted experiments with Boston
control many years ago. They got good radar returns from our glass
ships.
The problem is the slow speed we generally fly. Usually the center's
radar
uses MTI (moving target indicator), which gets rid of ground clutter
returns
and returns from flying birds. When Boston control deactivated the MTI
function, they could easily see us. Adding a lens to increase our
reflectivity would not help. But if we had doppler generator built into
the
lens (maybe a spinning wheel propelled by air; we have lots of that
available), the lens would be removed from the clutter notch. Maybe

Look up Luneberg Lens via Google.

We hung them on T-33 target aircraft in exercies to give a radar
return the size of a B-47.

You could make one out of foam and Rennels (sp) Wrap and put inside
your plastic bird and get a much larger radar return for just a few
ounces for the lens.

These are passive devices and no power is required.

Are we basically flying stealth aircraft?
