How to listen to a meteor !!!

Meteors burn up in our atmosphere at a height of 100 km or so, too high to directly carry sound waves.The American Air Force has a radar surveillance facility in Texas that beams radio waves into the sky. When a bit of cosmic objects streaks through our sky, the ionized trail it leaves reflects the radio waves, producing an echo. This radio wave frequency  is then translated into sound frequency, so you can effectively hear a meteor !!!!
