Microwave photons have less than a millielectron volt of energy, but it takes several volts of energy to ionize an atom of air. Microwaves are not considered ionizing radiation.
Now, it is true that a strong enough beam could ionize air by a multiphoton process, however a microwave beam strong enough to do that would also make the air opaque to microwaves and hence become useless for radar. So, we can presume the microwaves aren’t strong enough to do that.
Also if the beams were strong enough to do that you would see sparks and plasma, like the grape plasmas of youtube fame. But, no such plasmas are seen around the radar dish, where the electric fields are much higher than they would be miles away in the clouds where they could potentially modify the weather, or worse, around the feedhorn, where the electric field is much higher still than where it leaves the dish reflector.
The OP article is absurd.
From a link somebody just posted, https://www.youtube.com/watch?v=FiDHtOpWWcE it sounds like there are plasma fields (balls) that they create and brag about. And it sounds like there are space technologies using way, way more power than is necessary as claimed by people here.
It would be a good idea to look at that video because it seems like the claims being made here are gaslighting about what has already been widely publicly acknowledged.
Especially interesting how this guy’s reporters went to a seminar where they described stuff and then there was some spokesperson in public who claimed it doesn’t happen.
Sounds just like what I see from my government all the time. The suckers are the ones who believe them 99% of the time.
