Project summary

The Project's aim is an investigation into the phenomenon of radiowave absorption and scattering by:
1- quasiatomic complexes (QA) comprising a small conducting particle (charged or neutral) in the neighborhood of which f the electron (ion) is localized;
2- threadlike structures (TS).

QA and TS come into existence in the terrestrial atmosphere and open space Under the action of several factors, such as the disintegration of a moving ballistic object, affecting the propagation of radio waves.

The first stage of the investigation includes mathematical simulation of corresponding physical processes:

1 - solving the equations of electron motion when it rotates about the particle in the presence of the electromagnetic wave field with allowance made for collisions;
2 - solving the equations describing the formation of threadlike structures and quasiatomic complexes;
3 - analytical study of interaction of electromagnetic waves and these formations.

Following the theoretical investigation, laboratory experimentation is carried out aiming at the study of interaction between radiowaves and QA and TS as well as the elucidation of the mechanism of their formation.

Next, the full-scale experimentation is projected: radar probing of the formations generated by a disintegrating ballistic object, so that their physical nature could be identified.

The findings of the investigations can be used when solving the problems of long-range radio communication stability, as well as when employing radar for observation of varions objects in space and terrestrial atmosphere.

Thus far, the following scientists agreed to take part in this collaborative effort.
