      kek. I was thinking this same thing. the atmosphere reflects radio waves thats how they bounce signals over the horizon. cant they just see a "shadow" cast over the reflective atmosphere and see the plane?

        They can likely tell something is there, but it's not enough for a guidance system. Same issue as purely UV/VIS targetting really.

          Can't you launch a missile at the expected object location and have the missile use IR/Radar/Visual target acquisition once it approaches the expected target position?

          Your radar might not be able to provide tracking information from dozens or hundreds of miles away, but if you have a rough idea of where the plane will be the missile itself can have a multi-mode seeker sensitive enough to find the target within a handful of kilometres.

            Ok, so how do you tell a B-21 apart from a cloud?

            • 1 year ago
              Anonymous

              I assume the B-21 is moving at somewhere between ~500-1200mph

              I somehow doubt too many clouds will be clocking those speeds.

                Yes but WHAT is moving at those speeds
                You can’t motion detect, that’s based on air currents which are a fricking non starter that high up and at those distances
                Its thermals are concealed
                No radar cross section
                You basically have to rewrite the book on LIDAR to make this method viable

                I look forward to when someone devises some acoustic technology to scan the sky high up for the noise of stealth fighters, and the stealth technologies use acoustic-canceling to mute their engine sounds in counter. The technological arms race is neat.

                Stealth doesn't protect from the lower frequencies, but lower freq. requires a logarithmic increase in power for a strong enough return signal.

                Simple numbers, not necessarily realistic, just to get the idea across:
                1 Ghz radar can't see stealth (until it's too late)
                100 Mhz radar can see stealth, at 50 miles, with 50 kilowatt of power
                10Mhz radar -could- see stealth at 200 miles, but requires 1 megawatt of radar power.

                no, I genuinely don't understand why you think that's fundamentally different, the "visual spectrum" and "infrared spectrum" are adjoining bands of the electromagnetic spectrum and many sensors that can detect in one also detect in the other, imagine processing techniques don't care about your wavelength

                proof: point a TV remote at your phone camera and press some buttons

              • 1 year ago
                Anonymous

                Because fundamentally you can make materials that make shit hard to see in IR. Meanwhile the visual spectrum has distinct challenges when it comes to image processing that are not present in the infrared spectrum and so far nobody has managed to make a plane invisible.

                Also I feel you misunderstand the point. It's not about shooting a missile at the plane, it's about finding it in the first place.

            Yes you are describing doctrinal stuff which exists. This isn't a very effective idea however for a great many reasons.
            - The plane knows you are trying to target it because your radar is screaming, it can simply evade and your missile might miss by an enormous margin. Even a single degree of deviation at the ranges where air defences work, will mean a total miss.
            - The plane is probably trying to kill you, the longer your radar is on, the greater the risk that something like a HARM murders you.
            - Planes are fast, engineered to have reduced thermal signatures, and often operate in visually noisy environments. Electro-optical tracking (What you are describing as visual) is not yet reliable or cheap enough that it's a widespread guidance system, and it has very short range. Additionally, countermeasures to these future guidance systems are already rolling out in the form of dazzling lasers to kill any sensors built into the missile.
            - The more fuel your missile needs to burn searching on its own for its target, the less fuel it has to actually engage in a maneuver contest. Contrary to popular belief, planes can in fact evade missiles when they have an idea that they're coming.
            - You can't fit a meaningful radar into the cone of a missile. Any emitter large enough to detect a stealth aircraft even at very close range would be very large, and dominate the design of the missile itself, and also extremely expensive.

            And finally, cost. Surface to air missiles are very expensive, and very large. Shooting these large, expensive missiles at 'possible' targets which might actually just be anomalies, jamming, decoys, whatever is a great way to train your enemy to bait you into wasting ammo.

        admittedly I don't know that much about stealth and radar either, anyone who does probably can't talk about it anyway but in general finding a lack of return among noise is much harder than a big positive return
        Lots of things can absorb or deflect radar waves, the ionosphere isn't uniform. On top of that if it became such a big issue, stealth coatings would be tailored to mimic the background
