What say you, aviation experts and fighter pilots?
Well, I’m not an aviation expert of fighter pilot, but I have decades of experience in radar.
This, apparently is an imaging system presents an image to one aspect angle of the scene directly behind it. Take a picture of everything on your left side and present that picture to the right side. Anyone on the right side sees what’s on your left side. I have a close friend that was a PM at DARPA and he opined at some meeting this very concept. He was visited thereafter by a couple of investigators wanting to know where he got the information.
My guess is that this is optical only and it doesn’t work in the RF region (i.e., radar bands). Furthermore, I’d say this is only effective optically for a very narrow aspect angle of views.
“Not there” types of technologies spot stealth and have for several decades.
