Fine structure of the geminid meteor swarm from radar observations in 1988

Abstract

A method is proposed for the exploration of the fine structure of particle distribution in meteoric swarm cross sections. The method is based on the selection of stream meteors from the sporadic-meteor background and the treatment of record series by the statistical γ-criterion. The data of a meteor-radar measurements in 1988 demonstrate a nonuniform structure of the Geminids. © 1998 MAHK Hayka/Interperiodica Publishing.
