If you happen to have a VR headset and are looking to play around with the toys described in the article, I recommend VTOL VR. It has pretty low system requirements, and takes advantage of VR to create a virtual hotas (It is much more effective than you would expect). The physics simulation is, to my understanding, very good. And everything described in this article is present in the game to be played around with.
VTOL VR taught me about "Radar Notching". The article briefly mentions how radar can actively detect the doppler shift of targets. If you think about it, the doppler shift of the ground would be neutral, right? Or roughly the speed of the aircraft. So lets say you've been locked on by a fighter at high altitude and they've fired a radar seeker at you. Your backdrop is the ground, it can pick you out because you're moving so fast. So what you do is bank your aircraft to fly at a 90 degree angle to the oncoming missile. Now your doppler shift is the same as the ground and you blend in, the radar filters out the ground because of it's expected speed, which is now the relative speed you are moving. You get "notched out", and the missile will lose track.
