Meteor detection by radio

Using digital TV signals for radio meteor scatter

Admin October 7, 2025 No Comments

This is very relevant for modern meteor detection, since many traditional continuous-wave (CW) beacons have gone silent while digital TV (DTV) and FM broadcast transmitters now fill the VHF/UHF spectrum.…

What is Radio Meteor Scatter

Admin October 7, 2025 No Comments

Radio meteor scatter is a radio propagation phenomenon where radio waves are reflected or scattered by the ionized trails left behind by meteors as they burn up in the upper…
