About Meteor Scatter

Meteor scatter communications exploit the brief ionization trails left by meteors entering the atmosphere. These trails reflect VHF radio signals, creating detectable "pings" lasting milliseconds to seconds.

The GRAVES radar in France (143.050 MHz) is a primary target — its continuous beacon produces clear reflections off meteor trails visible across Europe.
