Outline of Final Research Achievements

This study developed the teaching aids for experiment of observation which do not have similar methods in the world. The novel observation methods can determine meteor parameters (radiant, velocity) using forward scattering radio waves from meteor trail. A meteor orbit can be determined from this obtained meteor parameters. The feature of the developed observation methods can determine a meteor trail without large professional observation facility. These developed teaching aids can be felt familiar about upper atmosphere, plasma and small solar system bodies. This may also fit active learning. Furthermore, in this study also developed the observation method suitable for outreach activities. As for this, many people may get interested.
