Looks pretty cool, though kinda "cheating" by pulling from adsb.fi - though I think you'd need something a lot more powerful than an ESP32 to receive and decode ADS-B ;)

I would actually expect the math to decode ads-b traffic is substantially less complex than, for example, a TLS connection.

It is trivial to decode, but don’t forget that tls is extensively optimised on most networking stacks.

Actually possible to receive and decode ADS-B on ESP32, but MLAT is failing (tried hard but not found a trick yet). Biggest problem isn’t that it’s not powerful enough, but the USB port bandwidth don’t match most SDR. Using some clever tricks you can receive parts of the message on a slower USB and be able to decode ADS-B

Why do you need to send the samples over USB?

Perhaps I didn’t read it thoroughly enough but it seems that lat/long of the “radar” are expected to be entered by user, I think using wifi positioning could be of great assist and could be done from mcu itself without involving web portal, though maybe portal already does it (didn’t get to see it)

“Finally, the firmware now supports authenticated OTA updates, so future builds can be installed through the browser instead of connecting the board over USB.” What does that mean?

OTA = over the air. ie online updates you’d expect of a more polished product
