    A drone can fly at ~100kph which is ~30m/s, giving you a whole half a second to do anything about it after you have detected its presence lol

    There’s alot of sensitive places that are remotely monitored, so having another means to sense incursion helps. It’s not always about stopping drone bombings

    Adjusts payload to provide a 50’ blast radius There. All fixed.

    More impressive, the same science group claims they can detect water emanating from clouds hundreds or even thousands of feet above them. This has led to the development of a new device, the “umbrella”, to deflect unwanted particles “raining down”.

    For my fellow non-Americans, 49 feet is just under 15 meters.

    I’m pretty sure we can all spot drones from 15 meters away with just our eyes and ears.

      I think the achievement is that they spotted drones from 15 meters away without using anyone’s eyes and ears.

      It’s impressive because it’s totally passive - radar can locate incoming drones, but also lets the drones locate the radar antenna. This new technique finds the drones without emitting any kind of telltale signal. So the drones don’t know they’ve been spotted, or even that anyone’s looking.

      So you could hook this system up to a vehicle, like a tank or a troop carrier, and integrate it with a turret, and now you have drone protection. Just look at the havoc Ukrainian drone wrecked on Russian tanks and you’ll see why this could be a big deal.

      Blind and deaf scientists develop amazing new way to “touch” a drone from 50 feet away using vibrations travelling through the air. “It’s like we’re sensing it from a distance”.

      New technique could potentially be developed further to allow people to communicate beyond their reach, potentially even from different (neighbouring) rooms in a house!

      Balanced coax cables wont affect the ELF magnetic field stemming from the physical rotation of the motors, which is what they’re measuring.
