What are /g/ thoughts on electronic warfare
>>101547618awesome, I wish I had a device to zap my neighbors music system or if I could dick around with the volume
>>101547618more like electronic warunfair
war drives global warming
>>101547618I like the sonic blaster that makes soldiers shit their pants uncontrollably
>>101547774didn't mythbusters deboonk that
Turned out to be almost useless on the battlefield, as the Ukrainian war demonstrates. Large stations jam their own forces, and when a drone loses radio contact it either returns home or ascends higher untill contact is back. Anti-drone rifles take several minutes to work and make the user and his buddies a target for the artillery strike.
Electronic warfare is when I spam nigger online.
>>101547655it's not really hard to build one
>>101547815At one of the RF villages I went to in India, I saw a PoC that can measure reflections off the rotor blades to do micro-doppler analysis to identify drones from their catalog, and then their system can send protocol-aware signals to disable or confuse the drone. This is way more effective than wideband jamming.As a PoC, it was interesting and they had only 3 drones in their catalog. I have no idea how well it'll work with a larger catalog.In any case, this requires knowledge about your enemy drones and it's useless against unknown drones.
>>101547618This is an occasional topic over in /cyb/.>>101547968>RF villagesWhat is that??
curious, whether megawatt tier amplitude modulation radio stations make comeback in event of war or not
A ponderance I've had; why don't they make radio jamming flares? They have those great big star shells they can fire out of an artillery piece to light an area, so why don't they have a radio equivalent? Would that just blast ionizing radiation over everybody?Also, how to radar detector detectors work? Can I defeat them from detecting my radar detector?
>>101547968>that laptopholy shit
>>101547783MythBusters are a bunch of jew faggots, don't trust anything they state is fact. show me a single article they've published? they're entertainers.
>>101549760why tho? lorawan has enough power for telemetry, uhf 433/915 for telecommand
>>101549784>A ponderance I've had; why don't they make radio jamming flares?Flares operate in the optical bands. They also burn out and drop to the ground quickly. Radio traffic can go easily on for days. The closest good faith equivalent are jammers in balloons and drones, both exist. ARM missiles, homing in on jammers, also exist.>They have those great big star shells they can fire out of an artillery piece to light an area, so why don't they have a radio equivalent?Barrage jammers are old fashioned, mess up your own bands, and are defeated by more advanced waveforms. At least a drone would loiter a lot more than an artillery grenade.>Would that just blast ionizing radiation over everybody?No, ionizing radiation is a very different part of the EM spectrum, from UV to X-rays and gamma rays. Radios operate at the opposite end of the EM spectrum.
>>101550111I'm mainly asking if there's a chemical way to make radio signals, since you can make light with chemicals and they're all EM anyway. And yeah I know it would block everything but if you've prepared in advance to fight without radio, doesn't that give you a drop on the other guy?How do advanced waveforms evade barrage jammers, how is that even possible? If the whole spectrum your gear can pick up is covered with crap, how would you be able to do anythong about that?
>>101550259>I'm mainly asking if there's a chemical way to make radio signalsMy man, here you are beyond thinking outside the box: you have put it on fire and kicked it into a vat of fuel. I can appreciate that.And I am all for good faith approaches, but the only way I can think of, is the use of chemical oscillators, which tends to be liquid, hazardous and won't hold well together when dispersed (if you prefer it delivered by artillery).I have never heard it used in practice or even practical use for chemical oscillators. Those were weird things I learned about in university and never heard about since then.I'll give you a reply on waveforms later.
>>101547968>Hindi on laptopMerry Morning, sirs.
>>101547618it has its uses but also vulnerable, the enemy can find it with a receiver and destroy it if it ever transmits any kind of RF that can be identified
>>101547783>tv show said no real :(get off my board
>>101547618meme warfare. so if I build a spark gap generator that produce so much RF noise, I could bring down a coordinated force?LMAO
Can't you just DDoS a drone? It's being instructed through a unique identifier, so just spam that identifier with garbage.
>>101547618The military industrial complex will probably start using gaymers and Steam to make parsable records of multiplayer games and then format it into tensors that neural networks can learn from. They will collect vast amounts of data and information from strategy to shooters. Then these neural networks will be used to coordinate and control vast swaths of drones with eyes and ears. Any real humans in the field will be forced to wear tracking and livefeeds, which will also give the AI additional eyes and ears. Even radio comms will be fed into its input, which it will have the ability to rapidly translate and decode if necessary.Basically a small super computer that could fit into a shipping container will have eyes and ears on the entire localized battlefields and be able to make autonomous decisions (assuming its given autonomous control over ballistic missiles and other vehicle systems).
>>101547618spread spectrum communications make it futile. but then again, we have nukes.

>>101547618> What are /g/ thoughts on electronic warfarewhy can't zoomers use apostrophes?
>>101550989No. You would instead invite an Anti Radiation Missile (ARM) for a quick visit. You would also mess up your own bands.You didn't think it would be that trivial, did you?
>>101547618>What are /g/ thoughts on electronic warfaregreat - if you know what frequencies to jam. don't know the frequencies or the target is using spread spectrum? kinda useless.>>101547968>that can measure reflections off the rotor blades to do micro-doppler analysisnothing new, used for decades.>india>, and then their system can send protocol-aware signals to disable or confuse the dronethat's fucking stupid. they don't all use the same protocols or signals. this shit is useless.
>>101547618>What are /g/ thoughts on electronic warfareits like you would ask "what are your thoughts on maths, anon?"its a tool.without additional context there isnt much i could say
>>101550259 >>101550332 >>101554474>waveformOK, I am back. As for advanced waveform, the best example is the C/A signal on the L1 frequency from GPS (Navstar) satellites. The signal is already below the noise floor even without any jamming. And on the same 10 MHz wide band, there are dozens of satellites transmitting. The trick is to use code division multiplexing (CDM) where the data signals and the clocks are spread by a pseudo random sequence (PRN), and the receiver has to lock on to that PRN with the right timing, thus recovering both the clock and the data streams.The maths is heavy but well documented on the net, in fact it is remarkable how much in depth GPS tech is published.Next up is simple waveforms, just need to make a few figures first.
>>101556652Next: simple but still useful waveform: CW.The amber part is the power budget for the jammer: either wide and low power, or high power but narrow bandwidth. Jammer bandwidth is from jammer start Js to jammer end Je.The red is the power of the signal (voice) you output, and the green is what you receive. So with enough power, you "burn through" the jammer, and can carry on the communications.When the jammer is too powerful, the Morse code operator calmly hits CW and reaches for the key. Emitted power is now into a narrower band (100 - 200 Hz, compared to a few kHz for voice), and the filter is as tight as you can handle (too narrow and the ringing is a pain). So the transmitter burns through the jammer, and the receiver has to contend with far less noise (the yellow jamming noise received within the green area).The more advanced Morse code operator will in brutal conditions select coherent CW and the filter is now 10 Hz and barely any noise will get through.All of this is public knowledge, and any good radio amateur book will explain the signal to noise budget. It holds for natural noise (QRN) as well as for man made noise (QRM).
>>101557558So you can just blast strong morse through a jammer? Is there not a powerful enough jammer to stop this?
>>101557558>>101557935Nevermind, stupid question, I thought harder. Of course if you have 2 of the 'most powerful ever' transmitters the one blasting simple morse through will have an easier time than the one trying to block the whole band.
>>101547618I had the chance to be part of this when I was in the army, but opted for other comms work. Wish I had of joined an EW unit.
>>101550014>>101550556
>>101557935>So you can just blast strong morse through a jammer?Yes, as long as the jammer is not directly on top of you.>Is there not a powerful enough jammer to stop this?Point jammers can be a problem, but the trick on the HF band is to hide.Some numbers:CW: 1 kW power into 100 Hz is 10 W/Hz. That doesn't sound like much. The jammer doesn't know where you will pop up and has to do barrage jamming over wide bands:Jammer, monster class: 1 MW into 1 MHz is just 1 W/Hz. It will kill most voice comms, but the operators will laugh in Morse code.
>>101557996>Wish I had of joined an EW unit.I hear that is where you find the Aspergers', both enlisted and officers.

>>101551925Spread spectrum, narrow band and directional.If you mechanically aim a shielded 40 dbi antenna at a satellite, what the fuck is a jammer supposed to do? The only signal which gets to the receiver needs to diffract around the shielding.
>>101563602I asked a not glowie question about not war, but nobody cares about radar detectors I guess. Just wsnt to drive fast.
>>101564583The jammer could be directed to the same satellite and hope to overload the receiver inputs. A large jamming station can drown the output from a mobile unit.It is known that various countries try to blind photo reconaissance satellistes with hihgj power lasers. It is reasonable to assume they try the same with satellite communication systems. Aviation Week (?) posted years ago that China tried to jam US drone radio traffic.
I would have figured shit like Bluetooth would be demonstration enough that radio use can be extremely resilient.
>>101564863There's a lot of satellites. If it becomes a problem, use high altitude UAVs instead. Much cheaper and you can have a ton flying around in international airspace.
