METHOD FOR GLOBAL ACTIVE-PASSIVE MULTI-POSITION RADAR OBSERVATION OF THE EARTH'S SURFACE AND NEAR-EARTH SPACE AND DEVICE FOR THE IMPLEMENTATION THEREOF

摘要

The invention relates to the field of radio frequency engineering, and more particularly to an integrated information satellite system. The technical result is to allow global continuous three-dimensional radar observation of the Earth's surface and near-Earth space with the potential for analysing events, targeting moving objects and carrying out real-time assessment of variables of the movement of said objects, and also to provide a global satellite system for personal communications, video broadcasting and broadband interactive Internet services. This technical result is achieved by means of the low-orbit grouping of relay satellites, in which a first group of satellites transmits signals of the personal communications, video broadcasting and interactive services system in an L-range, and a second group of satellites transmits said signals in an X-range, said ranges being designated for radar probing. In mobile communications uplinks, reflected probing signals are received in the X-range by the satellites of the first group, and in the L-range by the satellites of the second group. Information is transmitted via intersatellite communications links and radio data links to terrestrial receiving stations, where multi-angle radar images are formed and subjected to non-coherent integration and thematic processing.
