British soldiers take down drone swarm with radio wave weapon
- londons_explore 2y agoIf they were confident in this weapon, they'd let hobbyists come fly drones in front of it. They don't do that because unfortunately most kinds of directed energy weapons are fairly easy to shield against. Even external Comms is fairly easy to avoid jamming of as long as you can design both transmitter and receiver and use phased array antennas and a shared key in both.
- pjc50 2y agoUkraine felt it necessary to design fiber-optic cable controlled drones as a countermeasure, so I suspect the fancy radio solution isn't that easy. Or the enemy just jams the entire band.
- londons_explore 2y agoboth sides are using fiber optic controls because they're using modded hobby grade drones which don't have phased array antennas, and fiber is far cheaper than a phased array antenna on a drone which is disposable. But the next gen of drones will have phased arrays because they're things that are hard to design, and expensive to make a small quantity of, but when you start making 10M+ drones, they become cheap, and obviously have more utility than fiber.

- philipallstar 2y agoIt's run by Talis - isn't that private?
