Abstract: | Experimental and theoretical work on the transverse dimensions of meteoric plasma trains have not converged to provide generally
accepted values especially uncertain is the dependence of the train radii on meteor speeds. The roles of the meteoroid structure, fragmentation
and plasma processes such as ion–electron instabilities need establishing. Knowledge of the quantitative spatial distribution
of plasma in meteor trains is essential for a correct interpretation of fluxes and orbital characteristics. A current project
is described which employs the AMOR 26 MHz radar facility in conjunction with a frequency managed radar operating at longer
wavelengths designed to measure the ionization train radii, heights, atmospheric speeds and orbits of individual meteors. |
