Recently, the Belgian Institute for Space Aeronomy has been developing a Belgian network for observing radio meteors using a forward scattering technique. This network is called BRAMS (Belgian RAdio Meteor Stations). A radio transmitter emits a circularly polarized pure sine wave toward the zenith at the frequency of 49.97 MHz. This beacon is located in Dourbes (southern Belgium) and emits a constant power of 150 W. The receiving network consists of about 20 stations hosted mainly by radio amateurs. Two stations have crossed-Yagi antennas measuring horizontal and vertical polarizations of the waves reflected off meteor trails. This will enable a detailed analysis of the meteor power profiles from which physical parameters of the meteoroids can be obtained. An interferometer consisting of 5 Yagi antennas is installed at the site of Humain in order to determine the angular detection of one reflection point, allowing to determine meteoroid trajectories. We describe this new meteor observing facility and present the goals we expect to achieve with the network.
