Influence analysis of design parameters of low orbit early warning system based on STK/Matlab

The detection capability of space-based early warning system is closely related to the configuration of satellite constellation and is an important evaluation index that plays a decisive role. Aiming at the problem of early warning deployment and global coverage, the calculation model of early warning system deployment and global coverage under different parameters is established by means of the interconnection of STK and Matlab, and the simulation and numerical calculation of deployment problems are carried out in combination with the actual situation, and the restrictive relationship between the design concept of low-orbit early warning system and global coverage is analyzed. It provides some reference for the design of global early warning system.
