    “invisible radio wave”

    Whed have radio waves not been invisible to the naked eye?

    It uses high frequency radio waves to disrupt or damage critical electronic components inside drones, causing them to crash or malfunction.

    At a range of 1km…

    That‘s useful not just for drones. I wonder if this works against helicopters, too.

      It sounds like it’s a directed microwave cooker. Works on people too, just not ones behind good cover.

      Edit: ah, high frequency, my bad, it’s a gamma gun. Same principles apply I think, give or take the cover.

        They are definitely not blasting gamma rays to bring down drones lol. “radio” is a specific range of frequencies so “high frequency radio” is just frequencies at the higher end of that specific range.

        Gamma rays are insanely dangerous. I’m too lazy to do calculations/research to back this up but I suspect that gamma rays intense enough to reliably drop a drone would also give cancer/radiation poisoning to anyone remotely downrange (and also the operators). Furthermore, I don’t think we have a way to produce gamma rays in any high intensity in the lab. matter-antimatter annihilation and fusion bombs are the only way I know of for humans to produce gamma rays. The former can only be done at atomic scale in the lab and the latter is, well, I guess that also destroys drones (and everything else within 100km)

        High frequency radio is still below the visible part of the spectrum, gamma is waaay above it.

      More like: That could be useful, just not for (perhaps many) drones.

      1km isn’t that far - the drones that were used for surveillance of Minneapolis protests in 2020 were around 6km up.

      If they needed to get close for some reason, would a 1km deterrent be countered enough by approaching from directly above and using gravity for the last km?

        The drones used in Ukraine are basically just commercial drones with grenades strapped to them. And a 1 km distance they’re unlikely to be able to damage a target even if they detonated.

      Possibly because it’s presented how news used to be - a simple statement of fact without embellishment or click bait.

      Would you rather:

      Warzone’s always the best environment to test new battlefield systems.

      Look at the difference in technology between the beginning of the first world war and the end. We started off with essentially standing in fields shooting each other over distances you could spit, and ended up with tanks. The second world war gave us nukes.

      Will probably have AGI battle droids by the end of this war.

    I wondered how long it would take for them to figure this out. Or simply take control of the drones.

    Can we get the waves to produce “Hootie and the Blowfish: I only wanna be with you”? That would be quite epic.

      This isn’t just jamming signals, it’s microwaving the electronics from a kilometer away so it will work against fibre optic controlled drones as well

    The project supports more than 135 highly skilled jobs across the UK

    Is that 135 individual positions, or just some mumbo jumbo job titles they’re making up?

    The UK police can’t determine what is a legal 249gm drone or not as seen many times over with the auditors, so how on earth is this thing gonna work is beyond me?

    Just trash the airwaves I guess.

    How is knocking out drone swarms different from knocking out any other communications?

    I swear, such news are reminiscent of the notorious tech illiteracy in “Wraith Squadron” books from Star Wars EU. With that Bothan being, ya knaw, able to just check all of one planet’s communications from the orbit after arriving there. The author (not to insult him) didn’t even consider how preposterous it would be on our planet, which doesn’t know hyperspace travel and other SW-grade tech yet, to be able to process that amount of information, no “hacking” parts even being discussed.

    Which is even worse when pre-Wraith parts of the series are pretty sane and Corran as a character knows what he’s doing.

    Of course protocols used in such applications have DoS vulnerabilities that can be found and used. And a lot of existing equipment can be employed in that too. Just - why does the headline read so stupid.

      As per the article:

      It uses high frequency radio waves to disrupt or damage critical electronic components inside drones, causing them to crash or malfunction.

      Its not jamming the comms, its inducing currents inside the electronics of the drone to fry them.

      They’ve been using wire guided drones in Ukraine lately so directly damaging the drones is useful in cases where you’re not going to be jamming them
