It's cool space shit, is what I'm saying.
Edit: here's some video: https://www.youtube.com/watch?v=NTljlMH-0oM
Birds that flew over the parabola of the antenna or birds that flew between the focal point and the parabola? I can't imagine the amount of energy the former would take (and the latter is impressive by itself)!
During WWII, soldiers would stand in front of the radar to keep warm. This was before health and safety.
Edited to add in later years the soviets added one of the worst aerial radars ever flown (by the USSR anyway). Roughly the same performance as a modern marine radar. Think "Lowrance 3G level" performance. That outputs about 10 watts RF. (More like 20 watts DC in, and ancient microwave equipment was legendarily inefficient, so..)
Also the ground support vehicle runs the whole machine when the engine is off for ground maint, preflight, etc, and the max continuous is like 200 amps for the -21 ground support... so at 28 volts that's about 5 KW max for an entire aircraft.
Another way to look at it is tenth of a megawatt class TV stations were never surrounded by piles of dead birds. To shoot one outta the sky would take maybe 100 times the power.
So you're talking 10 megawatts out, minimum, given ancient RF gear that would require at least 100 megawatts power input... thats 100,000 horsepower or so. Also the waveguide feeding the antenna would arc over at those power levels, whoops.
This is why nobody uses beam weapons.
Also, this article made me realize how you can do frequency addition/multiplication on arbitrary signals via complex multiplication/exponentiation! That part of the flow graph really confused me for a bit. So cool!

Unfortunately most of the text they post is quite boring and detail less.
It would be nice if they added someone new to the team that was a better writer.
