RADAR SYSTEM FOR PRIMARY AND SECONDARY AERONAUTICAL MONITOR

摘要

Radar system for primary and secondary airspace surveillance, and more exactly for the detection and tracking of moving targets, consisting of a number of elementary satellites connected to non rigid structures and of a main satellite, which performs accurate measurement of the position and altitude of elementary satellites and real time adaptive combination of radar signals coming from them, so as to provide a large phased array operating in the microwave band. Such system overcomes the limitations on dimensions of large space-borne antennae found in literature, minimizing the incidence and effects of undesired echoes and interference & assuring high detection accuracy. The fact that the elementary satellites are all the same (modular) makes possible gradual assembly of the system with possible expansion in time and assures particularly high operating availability.
