gliders+radar

Bob

I played with rotating Lens some years ago in a project to develope a
high speed radar return that could be detected by Police Radar
Detectors without the results I wanted. I wanted to 'pin the needle'
on detector at max so true speed wouldn't show. (I'm a dirty old man
)

Your idea for gliders might work? Not expensive to try/test.

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.

Modern gliders are small and made of materials that show up poorly on
radar.

Are we basically flying stealth aircraft?
