This study presents a significant advancement in reconstructing meteoroid trajectories
and speeds using the Belgian RAdio Meteor Stations (BRAMS) forward scatter radio
network. We introduce an improved method based on a novel extension of the pre-t0
phase technique, initially developed for backscatter radars, and adapt it for continuous
wave forward scatter systems. This approach leverages phase information recorded
before the meteoroid reaches the specular reflection point t0 to enhance speed estimations.
Furthermore, we combine this newly determined pre-t0 speed with time of-
flight measurements to reduce uncertainties in the reconstructed meteoroid paths
and velocities. The robustness of our method is assessed using Markov Chain Monte
Carlo techniques and validated against optical observations from the CAMS-BeNeLux
network.
