French government is funding a demonstration of improved stealth technology for the Dassault Rafale fighter, with a focus on active cancellation techniques.

Active cancellation means preventing a radar from detecting a target by firing back a deception signal with the same frequency as the reflection, but precisely one-half wavelength out of phase with it. Result: the returned energy reaching the radar has no frequency and can't be detected.
