摘要
Abstract
With the advantages of short signal transmission links and high signal reception gains,the application of low earth orbit constellation with array antenna has been widely used in various fields in recent years,including 6G mobile communication and remote sensing.However,when array antenna on satellites in a low earth orbit constellation complete spatial scanning with the same beam direc-tion,the coverage on the earth ground only partially overlap,which may lead to poor efficiency of collaborative work between satellites in the constellation.In order to solve the problem of limited common coverage of low earth orbit constellation,a method based on Matlab/STK is proposed.The method can perform correction on the beam direction of array antenna at any satellite orbit and any moment.The correction table of azimuth and elevation of the beam are generated after simulation.Simulation analysis shows that this method can ef-fectively expand the common coverage of low earth orbit constellations,and enhance the coordination ability of constellations.关键词
