Abstract :
[en] Every day, millions of meteoroids enter Earth's atmosphere. Studying them provides valuable insights into the distribution and properties of dust and small bodies in the Solar System, the dynamics of the upper atmosphere, and the influx of extraterrestrial material to Earth. Their very high speeds also pose a significant threat to spacecraft. This thesis explores how forward scatter continuous wave radio observations can be used to reconstruct meteoroid trajectories and speeds. The work is based on data from the Belgian RAdio Meteor Stations (BRAMS) network. BRAMS offers several advantages over traditional radars, including wider detection coverage, higher sensitivity, and lower cost. Results demonstrate that BRAMS can effectively contribute to the systematic retrieval of meteoroid trajectories and speeds. This work paves the way for characterizing smaller and higher-altitude objects inaccessible to optical systems, enhancing our understanding of the meteoroid complex.
