How about a sea drone antenna that is a phased array pointing at satellites and the antenna on the sea drone is in a Faraday cylinder with the top off or a more standard Faraday cage (box) with the top off and the phased array low enough in the cylinder as to not expose the antenna to line of site with the ship while able to remain line of site with the needed satellites in the constellation? The only solution I can think of is flying assets from the ship that can get somewhat between the sea drone and the satellites. The idea is to have the flying jammer assets protecting the ships flying an optimized altitude sufficient to cover a large enough area on the surface of the sea without flying too high reducing the field strength at the sea drone. Of course, this is all theocratic and can be overcome with a sea drone with local target tracking for last mile intercept coupled with an INS for last mile and a GPS receiver using the same concept as the phased array.
On theory work but ... In videos of Ukrainian drones attacking tanks, it can be seen that they use 4 different frequencies and the jammers with several antennas on top of the tank don't do much work.
You could have a self contained drone that doesn't need an operator? Like many of our missiles fire & forget! It selfs guides using a programable map, IR, or INS and don't forget AI.
Yes, and then you could have anti-drone drones. Basically what you have attacking ships is a slower, cheaper version of a torpedo or cruise missile. What the ships seem to need is a slower, cheaper patriot missile system or phalanx gun. I suspect what will be eventually adopted is sub $1000 drone modifies with a dual effect shaped charge, one narrow projection down through the target to either sink, disable of detonate it, and a second that fires a disc-shaped spray of very small but heavy particles (kind of like those the iron dome system has been rumored to use) to try to damage or destroy anything sticking up from the hull. This relatively small drone would fly over and use a cheap thermal imager to lock overhead, then use lidar to control closure rate and proximity fuse functions. I suspect the Ukrainians might be able to produce a drone like that and sell it profitably at $10k per drone all up. No super-experieced drone operator needed, just someone who can launch it and fly it over the attacking vessel. Note that this would work equally well on manned boarding craft.
It's called ENGAGE, it's a collection of applications for counter-missile research.

So far, two years of drone war in Europe shows at best a 23% survival rate using shotguns loaded with buck. This is the highlight survival rate by far. Unacceptable
The video is about propagation effects on drones which use radio control and telemetry, completely agnostic to signal content and protocol. If you are saying that drones no longer use radio communication, no that's wrong.
😂and for will use this tesla coil ? 🤔 put a large tesla coil the boat and when the drone gets close the electricity will destroy it, is that what you mean??? and they will use faraday cage and you be dead ☠
U can't jamm self steering AI-powered drone that also might have a spool of fiber-optic cable as redundancy . I also would not publish even a simple solution on RUclips cuz I would sell it to DoD instead as well :)
Quite correct - only drones which use radio signals can be jammed. AI has other kinds of problems, as do fibre-optic spools. A common logical error I have seen many times: because we can't jam *all* the drones, there's no point in jamming *any* of the drones. Sell a solution to DoD: I used to think so, then found out they don't want anything they can't think up themselves.
So I guess to test whatever you've made, you either have to have access to a very good chamber, or you need a remote testing range, like going out to sea outside territorial waters... otherwise the video's title should be "How to violate FCC regs and acquire a felony bust." So this is aimed at amateurs? No- what use have they for this tech? Mariners? Doubful that they would DIY their own defense kit. Defense contractors? They already know how to do jamming, and are already releasing anti-drone products left and right. So again: _who is the intended audience for this video?_ Who will benefit?
FCC can only catch you once they get hundreds of complaints about cellphones or Internet being jammed , they then send an investigator near the area with a receiver in his van that detects frequencies . If your jammer happens to be throwing out these frequencies they will hone in on you and you end up with a hefty fine , so basically don’t use it often
FYI during a foreign war there are no laws about radio transmission in the conflict country, and we do not operate those jammers in our own territorial waters, with the possible exception of experimental tests. In testing circumstances a transmission license is needed, or we test elsewhere with permission, e.g. Iceland or Canada's far north. You ask a good question, "who is the intended audience for this video? Who will benefit?" Answer: anyone who has to do this type of work in circumstances where it's unacceptable to base the solution on guesses. The point is the methodology, not the jamming signal types or parameters. After the jamming signals have been determined (or an adaptive system to control them), a methodology is needed to accommodate the environment and the protected platform. Intended audience: - defence contractors - DoD technical staff who evaluate proposals - DoD staff who manage technical work - DoD and contractor staff who plan projects for next-generation technology - DoD and contractor staff who need to be technically knowledgeable to do their jobs - procurement and technical staff who need to determine if the protection provided is value for money, assuming anyone cares
I love your vids, you're always so informative. Looking forward to part 2.
Can modern jammer prevent an FHSS wideband (5 Ghz wide) radio signal to propagate?

Fantastic explenation, thanks!

Unacceptable
Me when survivor bias
A good start, but drones and comms have advanced way beyond what is described in this obsolete video.
The video is about propagation effects on drones which use radio control and telemetry, completely agnostic to signal content and protocol. If you are saying that drones no longer use radio communication, no that's wrong.
Tesla coil bro
LOL NO. Read a book about jamming theory.
😂and for will use this tesla coil ? 🤔
put a large tesla coil the boat and when the drone gets close the electricity will destroy it, is that what you mean???
and they will use faraday cage and you be dead ☠

Me. Because I think it's a fun and interesting subject.

An intelligent answer was already provided. Therefore I can say the intended audience is your mom, sir.
