    A 105-minute technical deep dive from Noise In Space evaluating whether Starlink satellites could work as synthetic aperture radar. It covers SAR signal-to-noise, amplifiers, antennas, duplexing, phased array beamforming and simulations of V2 Mini and V3 satellites.

    Cited as a rigorous radio-engineering analysis of what radar capability Starlink could plausibly have.

      Yeah, I agree. A massive radar network, passive or active is the most likely possibility I have come across. You'd need a LOT of compute at each node to get the most out of the network. I found this video[1] to be a pretty convincing analysis of the absolute max capability you could expect, and it would indeed be impressive. [1] this video

      Check out this video that goes into a very deep technical explanation about how the satellites can be used as a Synthetic Aperature Radar to build a realtime representation of the entire globe at meters of resolution: this video

      and soon from space? radio engineering breakdown of starlink radar capabilities, it’s a pretty impressive bird if you were designing it only for that: this video

      More like a giant military radar larping as an space based ISP. this video Elon has always been a Department of Defense/intelligence asset larping as a capitalists. You can't exactly go to congress and get a quarter of the government budget to do globe spanning surveillance from space, or convince them to let you fund, build and maintain a platform for psyopping your own civilian population (x) So you go get your illegal projects funded through capital markets with through an asset like Elon. As soon as the department of defense started focusing on subterranean warfare and how its the future of wars Elon starts a tunneling company. Elon is just Howard Hughes v2, they're running the same script again.

      The US, UK, AU, and Russia have been back and forth on leadership relative to some metric or another wrt Over the Horizon systems throughout the post war period. > the world's finest radar and navigation tech Hadn't realised the UK had a sat nav constellation up (nav tech) and .. are we counting Starlink as radar tech? * [LINK] * this video
