The starting cost for a drone show is around $20k USD, so it wouldn't be hard to fake what they are doing. It's hard to say if this a functioning system that can take down drone swarms, or someone is testing the market for a system that can.
- g-mork 1y agoThat seems a lot more complicated than simply using cheap unshielded drones against an ineffective weapon, but I guess it's possible
- sheepscreek 1y agoThey’re selling defence equipment to countries, it wouldn’t help their cause if this is just smoke and mirrors. It either works or it doesn’t.

- leoh 1y agoI’m intrigued. Elaborate?
- sheepscreek 1y agoIf you read the entire article, you’ll find a mention of an audience member pointing at a drone. Remarkably, the device/weapon was able to precisely bring that drone down without affecting any of the nearby drones. Clearly, they have something working for them. I can only imagine that it would be significantly more challenging than simply throwing a very wide EMP. Controlling an EMP is the seemingly impossible task, and they managed to succeed.
- stavros 1y agoTo be fair, they'd be able to do that even more easily with a drone show (ie remotely controlled drones).
- adrian_b 1y agoThis is not EMP. It is just a high-power microwave transmitter, made with gallium nitride field-effect transistors. Like any microwave transmitter, it can use a directional antenna. If the antenna is big enough, it can have a narrow enough transmitted microwave beacon to intercept only a single drone. The GaN FETs enable a higher transmitter power at whatever high frequency they are using. At lower frequencies, a 70-kW power was already easily achievable in the past. The higher frequency allows a precise aiming of the microwave beacon with an antenna of reasonable size.
- varenc 1y agoI believe they're using a phased array grid of emitters to electronically steer the microwave, not just a normal directional antenna. This means the antenna doesn't need to physically move to change what is pointing at. (within some bounds)
- hermitcrab 1y agoReally. A British fraudster managed to sell $20 golf ball finders as bomb detectors for thousands of dollars each to various militarys. He got away with it for quite a while. https://www.bbc.co.uk/news/uk-29459896 https://www.bbc.co.uk/news/uk-29459896
