The defense of a man-portable air-defense system (MANPADS) SAM is not another shoulder-launched surface-to-air missile. Silly.

The way I understand it though is the flares really didn't do much of anything as the SA-7 isn't heat seeking. Dude must have fucked up targeting or simply had a soviet left-over that was a dud.

The SA-7 is heat-seeking, in that it uses infrared guidance. It certainly does not use radar guidance.

The SA-7 GRAIL (Strela-2) man-portable, shoulder-fired, low-altitude SAM system is similar to the US Army REDEYE, with a high explosive warhead and passive infrared homing guidance. The SA-7 was the first generation of Soviet man portable surface-to-air missiles. Although classed as "fire and forget" types, the missiles were easily overcome by solar heat and, when used in hilly terrain, by heat from the ground. http://www.globalsecurity.org/military/world/russia/sa-7.htm

Yeah, the Strela-1 used, IIRC, a uncooled plumbous sulfide seeker. Cheap and effective, but limited to tail-chase against the hot engines of an aircraft, and was very "dumb" in that flares, the sun, and even some cloud reflections could confuse it.

I'm curious what the automagic detector system is. Millimeter-wave RADAR or UV?

Next-gen MANPADS use compact matrix IR seekers, they are much more effective against simple decoys. Still, direct blinding emitters that are used in most advanced countermeasures have a good chance too defeat such missile.

Modern MANPADS as I understand it also utilize an ultraviolet sensor to overcome thermal decoying. The idea is that the aircraft body will show up against the sky due to reflecting UV light, and more significantly the engine plume of a jet aircraft, especially one under afterburn, produces a significant amount of UV light.
Decoy flares, on the other hand, do not produce any UV.

So, when working together, the IR sensor may be momentarily confused by decoy flares, but the UV sensor will remain fixed on the aircraft and get the IR sensor back on track.

Blinding lasers remain effective, of course.
>> No. 109056 ID: d4c8ee
As I understand it, it can also work like blackbody radiation, with the UV seeker looking for the "void" created by the aircraft blocking natural UV light between the seeker and the background. There's also work into developing what is effectively a chaff made out of UV reflective materials that magnify natural UV light.
>> No. 109284 ID: ad9db9

WTF? I know for a fact that magnesium emits high levels of UV; why the devil don't they just use that if UV is what's being tracked?
>> No. 109292 ID: 9723b1
Something tells me the goal of IR guided missiles is to shrewdly make it so the IR detector is incapable of detecting the emission spectrum of any burning metal (not just magnesium) yet perfectly capable of detecting the emission spectrum of jet fuel burning at high compression ratios.

At some point the only way to defeat IR guided missiles passively and cheaply will be to throw out chunks of fuel and deflagrate them.

Until that point in time, small LED decoys can be made to emit the exact spectrums the missile is looking for, as long as a sample of the missile warhead was examined beforehand.
>> No. 109295 ID: 10f4c8

Because what the seeker tracks is the "empty spot" of the plane in the UV background of the sky, not the plane's nonexistent UV emission. It sees the contrast and follows the dark spot, while the IR seeker sees the engines and follows the "hot spot." If anything throws one of the seekers off, it error-corrects using the other one.

Pretty impressive system for something that fits in the tip of a cardboard mailing tube.

Oh fuck me, that makes way more sense than what I was thinking. Well, now I feel like an idiot for not picking up on that; thanks for clearing that up, though.

> jet fuel burning at high compression ratios

Just a clarification on jet engine operation: The fuel is only burning in the combustor and is done by the time it hits the turbine section. Also the pressure is atmospheric by the time it exits the exhaust section.

So from the tailpipe you get hot, high velocity gas. (1250'F according to the chart.)

I fucked around with a FLIR camera from work and found it to be kinda useless. Infrared radiation isn't exactly heat. It's like light that's generated from heat. So it bounces off shiny shit. See the runway?

Then there's all the physics bullshit about emissivity...

tl;dw: Air Force repeatedly sends aircraft down the same goddamn corridor every mission, Serbs use a IR camera to see when one is coming and then do basic math to find the intersection of two objects of unchanged velocity to volley fire SA-3s into the air until one of them gets close enough to trigger the proximity fuse.

It can still be useful to have an idea on which parts of an engine are heating up faster than the surrounding parts. (and i'm obviously not talking of the cylinders)
That way you have some idea where the loss/inefficiency in the system is.

Obviously not a solves-all solution, but it can help you get situated.
