Engineering Physics Annotation << Back RADAR-LOCATION OF ASTEROIDS AND METEOROIDOV IN THE ATMOSPHERE OF THE EARTH BY OF MATHEMATICAL AND SEMI-NATURAL MODELLING I.P. KOZLOV, A.A. RUKHADZE The asteroid and meteoroid danger regarding observation of these hypersonic objects (GZO) is considered. By mathematical modeling it is offered to defi ne radar characteristics of GZO in near-earth space. The direction of space researches of Earth by means of the radar with the synthesized aperture (RSA) and system criteria is offered at seminatural, mathematical modeling that allows to optimize RSA in land conditions, saving a half of fi nance and time for creation of RSA. In the atmosphere it is necessary to consider the physical phenomenon connected with emergence of an electromagnetic soliton. It is shown that land radar the system of meter range of radio waves doesn’t provide service of the low-fl ying purposes – the problem is solved when using space and air radar. Problem defi nition of a radar-location of GZO is given. Key words: mathematical modeling; semi-natural experiment; diffraction of electromagnetic waves on two bodies; system approach; radar-location. Contacts: E-mail: ikozlov43@yandex.ru Pp. 49-54.
