文摘

Forward scatter (FS) continuous wave (CW) meteor radar observations carried out during 1992–96 over the long baseline Bologna–Lecce in Italy, enable us to investigate the structure of the main meteoroid streams and of the sporadic background by the cumulative distributions vs durations of the recorded echoes. The trends of the mass-distribution of particles belonging to the quoted meteor complexes are discussed in terms of variations of the mass index s against echo durations and in terms of steady-state conditions for each meteor population. The mass index values of the sporadic background are generally higher than for meteor showers in the duration range of 0.1≤T≤10 s.
