Would this still work for modern military aircraft? I wonder if this + machine learning might still be useful, given radar stealth.
Many of modern aircraft is supersonic so acoustic detection would be useless, even if it technically works.

Most do not have supercruise, so they would spend most of their flight at high subsonic speeds.

#14Any idea why they're all pointed in the same direction, rather than different directions, in photo 4/10? https://dynaimage.cdn.cnn.com/cnn/q_auto,w_1100,c_fill,g_aut...

True (though stealth bombers are subsonic, just). What about headings that are not straight at you though? May still have value detecting things passing by?

You don't want to scan two angles at once. Direction is determined by probing different angles, not by the difference between two angles.

When 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 bette…

#20One of the more interesting things about sailing on Lake Mead outside of Las Vegas was that when conditions were right you could hear people talking on the beach more than a mile away. That you could weaponize this phenomena seems pretty obvious in hindsight.
