And now they can counter it yes

[–] rah@feddit.uk 22 points 1 month ago (2 children)

Probably not. They're just dumping energy into the electromagnetic spectrum, it's not something you can counter really. The only thing you can do is change the frequency band you use to move away from where they're dumping, which in many cases might not even be possible (the frequency band determines range, bandwidth, etc.)

Here's something I don't understand: Why don't they just make the drone target the jammer when it's jammed? That's pretty much the only signal that's clear as day in these conditions, and when it's done, there's one less jammer…

[–] HK65@sopuli.xyz 10 points 1 month ago (1 children)

RF waves go faster and further than drones. Drones don't have the range to target the jammer.

[–] bluGill@fedia.io 5 points 1 month ago (1 children)

Drones is plural. Even if most don't reach the emitter all you need is one.

[–] unconfirmedsourcesDOTgov@lemmy.sdf.org 1 points 1 month ago (1 children)

The emitter is 10 miles away and your drones each have a range of 5 miles. How many drones do you need to launch for one of them to miraculously double it's operating range in order to fly the 10 miles? I think I missed this lesson in algebra.

[–] bluGill@fedia.io 1 points 1 month ago (1 children)

Your drones, but what about the guy farther down the line who might be closer or have longer range drones.

[–] HK65@sopuli.xyz 1 points 1 month ago

The guy farther down the line got shot by a DShK because he forgot the reason drones are so effective is that the controller is out of range of other weapon systems.

you mean like anti-radiation drone? because in order to find direction of that signal you need relatively large (for physics reasons) and complicated (for practical reasons) antenna array. HARM has 25cm in diameter and is suited primarily for frequencies much higher than these used there. (higher frequency = shorter wavelength = all systems needed are smaller). here we'd need something 2x to 4x as big

also these particular jammers fuck up only 70cm band (handheld radio) and 900MHz band (used by some long-range drones), not even trying to jam normal fpv drones

Adding on to the other answers here, assuming the jammer makes the operator lose control of the drone then the drone would have to seek the jammer autonomously. Even disregarding the usual problems with autonomous seek and destroy bombs, since the drone is programmed to follow the jammer the enemy can move the jammer and effectively guide the drones, either far away until they run out of battery and die, or even worse back towards you / your allies

You mean like in CP 2077?

[–] ladicius@lemmy.world 5 points 1 month ago (1 children)

Yep. We will see wide bands completely unusable in areas of fighting due to DOS flooding.

I'm waiting for the wire connected drones and the relay drones for connections via laser.

[–] CarbonIceDragon@pawb.social 2 points 1 month ago

Wasn't there a story a bit back where someone, I think maybe the Russians but I don't remember, had been experimenting with a wire guided drone, but didn't seem to have kept going with it for some reason or another? Laser relays I wonder about myself though, it seems like an obvious solution, but I don't know enough about communication equipment to know how difficult it truly is to implement
