really not happy with this first answer I would try to merge the ideas behind these products 1. Flying Decoy. MALD (Miniature Air-Launched Decoy 2. Radar Site Seeking Missle. HARM Missle 3. Raspberry Pi Kit 4. Visually accurate Model Airplane

But if for some reason one of the decoys attracted attention and a radar was turned on to the decoy it could act as bait for a more expensive intercepter or it could start to hunt for the source of the radiation.

Then I would fly six F-16's over Mariupol six hours a day, everyday. Seeing an F-16 in Mariupol will be so freaking mundane, that nobody will take notice of the fake F-16's anymore. An F-16 over Mariupol will most certainly be a false alarm.
