I mean, do you want analog or digital? I remember I stumbled uppon a “guide” on how to build the digital part of a radar. That part would cost something like $10k. Probably less if you purchased used.
probably not that hard to imitate chain home since you just need a VHF beam/transmitter and point it at the sky with an oscilloscope. That's how Watson Watt did it.
the FCC would thunder fuck you though.
I forgot to add that the original test rig for chain home was a BBC shortwave transmitter so any HAM setup could probably work but you'd be spamming bullshit into shortwave broadcasting bands.
>HAM
You know when you see someone use this word capitalized like this, they've only just learned about the hobby 15 mins earlier.
yes you've caught me
I'm not a middle aged sperg with no friends so I don't actually care about the specifics of a boring hobby where no fun allowed boomers talk to each other and suck up to FCC by ratting out anyone who isn't licensed
Forget WWII, what does it take to build AESA?
I went looking for radar units to put something on an autonomous drone and couldn't find anything that wasn't a simple altimeter or single point range finder.
>what does it take to build AESA?
teams of design, electrical, systems, software, mechanical and materials engineers and millions upon tens of millions of dollars of salaries, equipment, raw materials and electronics.
Can you buy a AESA board like you can a flight controller?
I don't mean something that sees fighters 100km away, just something that can identify other drones inside 100m.
Then you can do it with 3 guys and $2 000 or so. Read ieee papers they explain how to actually do it.
doesn't scale like that. as your number of elements go down, your precision goes down. element size is dictated by wavelength.
so you either have a big panel and a lot of elements, or shit precision.
This is how you do it you need a processor that is like 10k. Fucking crossconected fpgas todo highspeed furrier analysis and shit. Its hard as fuck but doable. But people notice when you start systematically shooting radarwaves from somewhere, and lets just say a f35 or 10 will investigate the disturbance in the force
Can you wrap wire and soder vacuum tubes? If so, you could make any WW2 electronics.
honestly pretty achievable. it wouldn't be easy or cheap, but I figure an intelligent and handy person with lots of money could learn enough and probably get something working in a couple years of full dedication.
Its possible to make 15mile radar using high res digi cameras+lenses with computers and Ai object recognition.
Its what multiple Space agencies already use and its cheaper and easier to use than radar. Of course it works differently in "space" as it would work on the ground (given height of the EYE)
That really fucking depends on what you are looking at. And cheap is a comparative term. Cheap compared to what
Are you talking about ELF radar?
No such thing.
>verification not required
KrakenSDR offers something called passive radar. After release of the source code somebody found out it is violation of export controls so they pulled the source code. It is still out there. Just need a krakenSDR and a nearby radio transmitter such a TV tower or FM transmitter. FCC can't do shit since their broadcast is licensed and you're not transmitting
Passive radar isn't unique to the krakensdr. Any moron with 2 rtl-sdrs can achieve something similar.
