Electronic Warfare: The Invisible Battlefield 

That elephant scared the shit out of me.....

Your "elephant" always gives me a heart attack.

A short and quick class of EW lol, I remember when I was teaching all this stuff and my students never understand me, thanks for the video.

Thank you for covering these topics, on RU-vid no less.

As someone who’s always struggled to understand this stuff, one way of describing antennaes that helped me understand their passive nature was hearing them described as to a signal what a lens is to a light source

An easy way to think about antenna gain is to compare it to an antenna that radiates in all directions. If you have 1 watt of energy going into that specific antenna, that 1 watt gets sent in all directions at once. If you put that 1 watt into a directional antenna, all that energy goes just in one direction and the receiver sees a higher signal level. Its like cupping your hands over your mouth to shout. You aren't amplifying your voice, you are just making it all go in one direction instead of everywhere.

I had to look twice at the channel name because I thought this was a DCS video in my feed. I'd recognize that cockpit anywhere. 1. Nice tie. Love the matching handkerchief, too. 2. This is going to be a great series.

citing the hangover, electronic warfare and Otis... it happened again! When they take control it will remain clear that I was on their side😂

Ooooh, hold all calls I require 20 mins! The best channel has uploaded. In fact make that 40 mins I may require 2 watches to get my head around this most interesting topic.

Expert interventions from guru Otis, as well.

I loved the elephant 😄. Very well researched. You put a lot of work into that

2 days later this gets even more relevant!

Thank you for another exemplary video. Cheers from NZ🇳🇿.

I am glad to see you are back! The elephant in the room had me ducking.

wow, lots there to understand! I’m going to have to watch it again. my cousin made his living designing antennas. He probably thinks it’s old news.

There is an old (1985) but still good book on EW by Doug Richardson. Salamander books. Update: Title "an illustrated guide to the techniques and equipment of electronic warfare"

Excellent video as always

Great vid. Complicated stuff and you did a good job explaining it. Looking forward to more on this one.

Thank you! I’m looking forward to the rest of the series 🥳

I swear, even after reading the other comments... THE ELEPHANT GAG STILL SPOOKED ME. Great job. ;)

The first 20 minutes of your presentation reminded me of a course I had at university, EE 342 or 344 -- Digital Data Communications I, that I did very well in, having had interests in Control Theory and a great class/teacher of analysis in the frequency domain. My grade-point average climbed dramatically over the final two years of undergraduate engineering courses, much to my surprise and to my advisor's amazement. I struggled through the mathematics and physics during those first two years, but once I began to study practical EE, everything began to make sense It was the year 1980 (+- a year or two), when I finally got to those upper division electrical engineering courses. I traveled the long road to get there. Live and learn. I do hope youll have a follow-up to this introduction. Antenna length and structure is essential to maximizing S/N whether receiving or sending a signal. I'd be interested in learning how the integrated computing power of the F-35 and the hive manages signal ID. Much can be done between pulses. Also, how does the AESA act in the system, can the "sensors" be optimized to improve signal quality via clever engineering/software tricks that tune these components to discriminate between the many hopping radar techniques used by the bad guys. Many more questions. i hope to learn more... Merci, Monsieur.

Would love to see more on EW

This channel never disappoints ! Top notch quality content !

A perfect example is an USB RTL receiver. I even managed to have my own TCAS display seating in the plane last row and ACARS receiver with proper software. Anything below 1Ghz can be analized. Great video, elephantastic.

Very informative! It's really difficult to find this kind of information in a way that isn't too technical for the average person and you do a very good job at explaining it. Looking forward to see more of it!

The Elephant bit was funny 😄

Finally someone who GETS IT :). Thank you millennium 7 again :)

Wow, thanks so much for covering such a fascinating and so very rarely explained topic. Most interesting video I’ve seen on RU-vid in a long while 👍

This is easily the best video on this subject I have ever seen.

electromagnetique waves and good vibrations !!!

well done! not simple to simplify...you pulled it off very well. very good job on video production as well.

Finally... The video that puts shiny aviation equipment into operational context: the *'Friction'* of warfare.

THANK YOU!!! Been asking for this for awhile!!

He is always in the room - you never know when you'll notice each other

I am already worse than useless when it comes to understanding electricity. All of this is arcane knowledge that I can never hope to fully comprehend. Still a very concise yet thorough EW 101 lecture. Excellent work.

I’m really looking forward to this series. I can’t imagine where else I could go to get this information. 🙏

Just noticed...Congrats on 100k 👍

Wow man, nice! I have been waiting for this since you've asked the viewers if we wanted you to cover this topic. Nice introduction to the topic and can't wait for the continuation. I hope you are doing well health wise, take care.

Excellent video, thank you. Great groundwork to help understand the more complex issues to come.

I always look forward to your videos. So many good sumations of important aspects of modern air warfare doctrines and technologies. Know that we all appreciate your what must be hard work

Looking forward to the rest of the series. It would be nice to see a deeper treatment of scan pattern analysis and de-interleaving techniques.

Great stuff as usual, keep up the great work

10:27 Hah, those soda and sports drink bottles and the tablets tell me roughly how recent this footage is, but those keyboards and the Microsoft mouse speak another tale. :D

Fantastic to see detailed analysis on this topic, lots of great insight into this critical but often overlooked topic! Even with no technical background, it is great to see the level of detail you go into, bravo!

Just fascinating. Enjoy the way the material is presented and that I understand it.

Thank you kind sir with a cool tie 🙏 this is the most comprehensive video I've watched on this topic.

Otis and Alfie: Dynamic duo!

Best youtube channel. Good health and long life to you my friend.

9:01 I'm subscribed to your channel and saw it listed as a bullet point in the opening slide, and yet it still got me! Damn your eyes, sir! *✊🏻* 😆

Awesome video and great topic! Love to hear more on this 😊….adding the ‘girls’ was nice too LOL

I agree completely when you mention other RU-vid videos. They always delve into the topic through a historical lens and the analysis is narrow and shallow. They neglect to tell how, why and most importantly nitty gritty math and science behind the technology, even when talking about modern systems in which the science is THE most important thing to talk about. When looking for well made military oriented video with a high production value from the biggest channels on RU-vid, you are more likely to find a video that is, in all intents and purposes, a history lecture rather than a science video. Don't get me wrong, I do not dislike those videos but most videos I have seen, with a few exceptions, is at least 60% historical exposition. But alas, those are the videos that get all of the reaction videos because history is more easy to digest and understand in a short video than science. I've been trying to recommend your channel for reaction videos from other people on RU-vid because this is the information we need to better understand the MODERN battlefield which has evolved since the romanticized battlefields of WW2 and even Desert Storm which happened before I was even born over 30 years ago.

Great lesson!

I loved this, thank you! subbed etc so no future vids slip under my radar.

Wow great video. these things get very complex very quickly

Nice explanation. Mostly correct. I think one item that is neglected is the directional parameter for the receiver antenna. One receiver and one antenna may "stare" in one direction continuously, and cover a lot of spectrum all the time. That comes to 2 dimensions, one for frequency and one for time. But then in an environment like the Black Sea, it may be important to also "stare" in all the directions over the surface of the sea - 360 degrees. So we add a 3rd dimension for azimuth direction. If we also want to cover airborne signals, we might also need to cover elevations too - another dimension gets added and we are up to 4 dimensions. But it does not end there. We might also want to include polarization. This would be an additional dimension. When you think about the problem of signal detection, it gets quite complex. We did not even consider various spread spectrum technologies that distribute signals across time, frequency, space, and polarization, in order to avoid hostile detection, or jamming.

Thats no elephant thats a woolly mammoth 🦣👀

Excellent video! 🐘

Fantastic.

In WW2 and ongoing, the signal intelligence took mainly two forms. The first was an intercept of a message which could possibly be decoded. The second was just monitoring the origin and volume of traffic in an area. A lot can be learned just from considering this traffic data. It was one of the reasons a dummy army was set up prior to D-day with a very active radio scheme. The convenience of radio communications was a big window into enemy operations. Phone lines were more problematic.

Good construction Thanks.

Thank you, Gus. Interesting video.

What’s gray and really loud? A yell-ephant.

I spent 20 years maintaining ECM systems for the USAF. anything you can find is probably 10-20 years out of date as a minimum. Stuff I worked on before i retired in 1992 have not shown up on the internet yet. Even one system I worked on in 1971 in Vietnam is not public yet.

incredible video with insanely interesting content once again ! i missed my daily train because of it 😂

I have been expecting this

Thanks 👍😊

Very cool

Epic elephant Entry ❤

very interesting ! :)

am pretty sure the elephant jumpscare took 6 years out of my life expectancy lmao

Thanks for fixing this! ;)

thanks

Thanks!

Term GAIN can be defined as gain in signal to noise ratio. The signal itself can be attenuated, but makes it esier to isolate signal from noise in spectrum.

Never forget the story behind "99 luftbalons"

Great video. I think those British aircraft were mainly doing racetracks over Romania according to flightradar 24

Have you ever considered installing a radar antenna at the back of the vacuum cleaner? Or never mind. Just get a cat.

I remember learning some of that stuff when i was assigned in the EW division in the army. But most of my time there i was simply listening to friendly comms for protocol breaches and man... half the army would get court martialed with all the breaches on a daily basis if any of us decided to send just one tape to HQ instead of reporting that all is well. One guy even turned the radio on his outpost in a radio station, broadcasting songs and talking about sports, that one we couldn't cover up cause HQ got the broadcast too.

Awesome....as always. Can you plz make a video on datalink and software defined radio. And the elephant......🤯🤯😱🤪

Never stop with that elephant hahahahaha

Aww! I quit my job before you told me not to! 😂

Also satellites, ships, embassies, sea cables, tech companies

It will be great to have specific video talking about this. Most sources I can find (with some exceptions), are at best from early Cold War. After 2nd half of the 60's most of it is becoming "still classified". Or at least hard to find.

Honestly this a problem with like videos on cybersecurity as well. Im convinced that most ytbers have no idea what they're talking about so they simply don't explain the actual concept and only ancillary effects of the technology. Or numbers and dates like you say.

Olala, you are liking every comment❤ Good job, Good Sir.

i was offered EW when joining the army 20+ years ago, im kinda bummed out i wasn't able to actually get into it (i was medically discharged fairly early on. yay for ultra rare conditions). I have a friend now who did this for a while in the air force and other civilian government rolls, it amazing seeing his man cave and some of the toy projects he is getting up to, its amazing to see what a $10 Arduino board and the right radio gear can do, he has set up a system that's 100mw, gps, powered by RF if its near something like wifi or just a small battery that's meshed and can transmit and receive over 10,000 KM if on 4meg or vhf over about 5/ 10 km. its can RT/TX small text messages with time stamps and gps location, very handy for locating that lost puppy or something lol Similar gear when you know the someone has arrived because basic signal tracking/ detection that's received from their phone. so for example in a large crowd at a political event these things would be scattered everywhere could locate and ID a person/ device and map and triangulate its location using their phone / watch / car with sim card wifi Bluetooth etc

Grazie.

Guess my heart is ok. Jump scare!

Wtf is up with that elephant. I was listening to this guy trying to sleep when the freaking elephant emerged from nothing!

Allow me to point out, that one doesn´t wear a matching tie and pocket-square in men´s fashion. Great video as usual though.

You should make Physics lessons for High school and Uni. Would help a lot

Once you get on it, you can't get Offutt.

That’s what happened to the AT&T network

Magnetrons can help protect aganist drones.

Hi Gus. I think it is time for a preliminary analysis on the Turkish Kaan fighter jet.

If I may suggest - I know it's already a "long" video, but it would be better if you spoke a bit slower. I often have to pause to read something on screen and since it's going fast, it's better to pause. But then I need to rewind to remember what you were talking about and because you're going so fast it is often hard to follow what you're saying AND read stuff on the screen at the same time. You also don't have to make smaller notes show up for half a second - because it again forces me to pause, go back, read it and I'm lost in conversation. Thankfully today stuff was pretty basic - so I technically knew all of that, but I suspect that if this continues, there will be topics that will be much tougher. And I did have to watch certain segments of video 4 times, due to text, speed of delivery, speed of text disappearing from the screen and pauses. OOOOF. Big fan - I really hope more people watch your videos.

👍

Millennium 7, love your videos, but please, when you flash some text on the screen, leave it on-screen long enough for a person read or to hit pause without needing to rewind.

I wish I was knowledgeable enough to understand exactly what you were saying but I’m still able to enjoy what you’re talking about if you can understand what I’m saying. What type of work do you do?

The electronic warfare industry... yeah, right, in my dreams 😅 I only had two courses on communication subject, tho I really enjoyed the syllabus, I only managed to score just high enough to pass the exams... that stuff takes serious computational prowess... I'm good, but not that good...
