-JS9 web viewer enables viewing only the first two records. A specialised application is required to see the rest of the records. The description of how the data files are sorted can be found on [[en:convention|directory convenctions]] webpage.

 Following on the area of the head-echo signal there is an area of a static reflection from the meteor trail. Its intensity varies in time. The change in intensity is caused by a progressive recombination of the plasma trail of the meteor and the periodic changes in intensity are caused by a space modulation of the radar signal. Following on the area of the head-echo signal there is an area of a static reflection from the meteor trail.
