Active Radar Homing - The Guidance of the AMRAAM, MICA, R77 etc. 

What are the cons of active radar homing?

Thank you very much! Much appreciated! Radar is something I am planning to cover in the 4th season of the series dedicated to the AAMs but, depending on people's interest, it may be brought forward or covered by some of the short videos.

@@Millennium7HistoryTech sounds great. I'll look forward to your videos!

How hard is it actually to understand radar systems? It's easy imo

@@varunkoganti9067 well, for the technically inclined, there are a lot of good resources. But a lot of the military specific stuff is still classified or the technical stuff is not fully grasped by the common person. That's why most other RU-vid channels just focus on the impact of the stuff, rather than fully going into the physics part. Or they take the dramatic approach

I live in Cali, so this is highly regulated...good vid tho.

Well, I consider this a very high praise. Thank you!

My Pleasure! What did you find particularly interesting?

@@Millennium7HistoryTech pretty much everything because I learned alot. Are you planning to make a specific video on missile trajectory? because you didnt mention the missile pursuit in detail. I know there is pure pursuit, lead pursuit,lead collision and propotional navigation. And thanks for this awesome series

I am a bit torn about it. It would require showing some mathematics and explaining it on video. I need to find the courage to do it. I need to have some hints that people like you would follow along...

Thank you very much! May I ask why did you have to explain it in the context of these two games?

@@Millennium7HistoryTech I lead a wing in a squadron in War thunder, where we fly jets competitively against others. War Thunder has recently been expanding from primarily propeller driven planes from early ww2 and on to the early 1st generation jets, to now include planes like the F4 Phantom and its contemporaries. Along with these new jets, come new weapon systems like IR-guided missiles from the Aim9-b/e/d's, R-13s and up to the British SRAAMs - with radar guided missile weapons like the sparrows on the near horizon. Since many are less familar with the underlying mechanics and princibles (being used to only rely on convential guns/cannons), and because the game itself does a very poor job at explaining these, many have found them to be lacking, until they understand these. This is where your videos have been a great insight to many of our players :) DCS adds in even more of a simulator expericence in playstyle, and with much more advanced weapony available. This means the gap between the people who understand the weapons, how the work, and their limitations, and the ones who do not, becomes even more significant. The average joe who plays these, obviously doesn't have your years of training/expertise (and neither do I for that matter, besides on a personal interest level), so even figuring out where to start looking for information to gain an overview can be a challenge. You make really nice and informative stuff, and its a good mix of information both for people who are more studied, and the people who have no prior understanding - but a willingness to learn. Basically summed up, your videos and the lessons in them, give us an competitive edge over the people who don't take the time understand :)

@@Ragnaroz6000 I suppose I am flattered for this... Looks like a video about the tactics and the aerobatics could be useful to you guys ... one day!

@@Millennium7HistoryTech We would definitely watch that, Sir! :) Keep up the good work! :)

@@Millennium7HistoryTech Please make a video about: Python-5 I-Derby I-Derby ER Spyder Air Defence System Looking forward to seeing that video on this Channel!

They can be part of an overall strategy to defeat stealth.

Military aircraft have Radar Warning Recievers. These detect the radar energy from active radar. Some aircraft have Missile Approach Warning Systems, which can detect missiles based on their natural heat and UV emissions and reflection. These systems will automatically deploy flares and other countermeasures, while also informing the pilot.

Radar points forward

the compresed air in the front of the missile is a big termal signal

Yes, data link

Modern solutions are pulse. The pros & cons is really too complex to be discussed in a comment. But there will be time in the future to go back to it.

If I interpret correctly point 1, that is not how it works. Range is defined by the energy and the fire solution depends from the launcher. An F-16 can acquire a track by the rada, and the range at which it can be fired upon depends from the weapon energy. The range difference between Sparrow and AMRAAM depends from the models, obviously. Point 2: it is not an advantage because AAMs do not fly vertically up and they already have energy from the launcher. They do not need to overcome their weight, they need to overcome air resistance and shedding weight, in this case is not a particularly large advantage. Also, the stage junction is a weak structural point and so high G maneuvers are not possible while it is attached and so, at short range, it would not be very effective.

Hi Jesus. This question is a bit OT but I can try to answer. However, would you be able to make an example of what you are thinking to? Which kind of situation would be the one you are interested in? Is this a cruise missile vs SAM scenario?

@@Millennium7HistoryTechsorry about the delay, something like this: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lDKnKPcxfL4.html what is the difference in technology between the defender's system and the attacker's missiles? are they really able to compete? or is this just a waste of missiles?

@@Hulnbfrijabl missile interception is complex, while a missile can hit target with the help of pre loaded target coordinates or if you want to hit a moving target you need some kind of secondary guidance like active radar seeker. To launch a land attack missile you don't need any radar, but missile defenses need surveillance and fire control radars, command/control unit and missile launchers to intercept targets.....

Umm ok. You seem to know way more than me cuz I'm getting what ur talking about but not familiar with the systems u described. But good on bud 👍

AESA refers to a specific configuration of the radar emitters and antenna, which gives some advantages in terms of beam shaping and overall beam control. It also tends to be more reliable because it has no moving parts. An "average active homing" doesn't exist as such. A more conventional configuration may do just as fine if you don't really need the AESA features, like it may happen for a missile.

Thank you very much! Much appreciated. To keep the lock, the missile (but this is true for every radar) must compare at least two samples and act accordingly. The first sample returns the target echo. The second sample is a bit on the right, the third a bit on the left, the fourth a bit up, the second a bit down (there are scanning patterns but for sake of simplicity let's suppose it is just like this). If any of the following samples return an echo, then the target has moved. Say the left sample returned an echo, then the target has moved a bit left respective to the radar. So the next 4 samples will be around the position of what was originally the left one and the cycle restarts. It is easy to understand that, in this way, the radar follows the target.

@@Millennium7HistoryTech thank you very much sir i thought before like this but i was not confidant and didnt have enough knowledge. thank you sir for your efforts i learnt more from your posts i am thankful. yes that will be very useful too, to make a video or animation about the physics of keeping locked missile on target , in future .

Please invent a sensitive microphone that works at Mach 5

Because the missiles fly many times the speed of sound this would not be appropriate and if the target was super sonic absolutely useless.

Too low frequency

Classic style being getting shot down ?

AIM -54 s are far as Americans. They were designed to intercept heavy russian bombers.in layman terms they're fat like Americans.

@@varunkoganti9067 YES . Almost all russian copied weapons are BIG - FAT - UGLY - UNRELIABLE.

You forgot the F-14. Technically speaking you are right but those systems were not used as a replacement for the radar like modern IRSTs. In the video I didn't really mention those systems because I don't even consider them real IRSTs, they were more of a sort of infrared sensor. I could have mentioned them for clarity, so, thanks for doing it for me.

@@Millennium7HistoryTech Yes, I was thinking about the F-14, but my focus was on the 60s. The F-101B IR Sensor does bare a resemblance to the SU-27 and MiG-29. Obviously not as capable.

It is an old video, almost two years old. If you feel like, you can watch more recent videos where there is no problem.

He is Italian he told by himself once

The dark blue suit by the way adds the Italian touch. I loved Italy every time I visited it...Bella Italia and your 'Ars Vivendi'.

Interesting, do you have a source? I would really like to learn more.

Not necessarily. The AIM-54 Phoenix would lock on the last 10 seconds of an engagement. 10 seconds is NOT a lot to time to react and especially if the missile is DIVING DOWN towards you at Mach 4+. Yes, your RWAS will notify you of an impending attack, but it only shows bearing and a symbol, not altitude.

@@Networkguyinsavannah The Phoenix required targeting info from the launch plane to get it closed enough for the last 10 seconds. Do, you're still illuminated.

@@chrisrautmann8936 you can, but most likely you are either in a Search while Track scan mode or a Pulse Doppler Mode

@@Networkguyinsavannah Either way, you're radiating. If they know the frequencies you radiate on, they have receivers that can alert. And based on espionage effectiveness, they're going to know those frequencies in pretty short order.

You don't get a launch warning until the missile goes pittbull. If the missile dosent go pitbull until 1-2km the pilot won't have time to react.

@@varunkoganti9067 what is that mean by missile go pitbull ?

Consider yourself told off! 😆😆
