Would this still work for modern military aircraft? I wonder if this + machine learning might still be useful, given radar stealth.

- SiempreViernes 6y agoI think much of the usefulness is tied up into the sound arriving substantially before the plane itself.
- TomMarius 6y agoOr you have a network of sensors?
- nephrite 6y agoMany of modern aircraft is supersonic so acoustic detection would be useless, even if it technically works.
- Sosh101 6y agoTrue (though stealth bombers are subsonic, just). What about headings that are not straight at you though? May still have value detecting things passing by?
- Ididntdothis 6y agoWhen I was at military I attended a few exercises where jets were involved. They don’t go supersonic but pretty close to it so usually once you start hearing something it’s almost over. It’s actually quite terrifying to have a jet coming at you at 800 km/h at low altitude. Very surprising, then very loud and incredibly fast. You also hear passing by jets only once they are long gone. I assume radar is just much better than sound.
- jacquesm 6y agoNot just jets, a regular propeller based plane can have that effect: https://www.youtube.com/watch?v=4iOoiEbtf2w https://www.youtube.com/watch?v=4iOoiEbtf2w
- Ididntdothis 6y agoNow double or triple the speed, make it much louder and you have a jet.
- foldr 6y agoMost do not have supercruise, so they would spend most of their flight at high subsonic speeds.
- rtkwe 6y agoThen it becomes a battle between the detection range of the audio sensors vs how long the attacking craft can spend supersonic. They could spend the last phase of the approach supersonic and even transition then turn to make any tracking useless.
- dylan604 6y agoIf they are supersonic, would you just need to increase how much you lead the weapon. Supersonic doesn't mean they're quiet, they're just further ahead than where you are hearing them. Or am I just totally making stuff up?
- SamReidHughes 6y agoDetecting helicopters would be one situation where it could be useful for mobile troops on the ground.
