A Beamforming Scheme with Steering and Nulling Capabilities for Direct Radiating Array Based Satellite Antenna

摘要

In the current satellite communication systems, the multi-beam satellite system has been widely used. This paper analyses the typical fixed multi-beam system and designs a simulation program called DRA for beam forming. The beam can have any directivity, and can eliminate interference with the null steering in a specific direction of the beam coverage, enabling users to communication with a beam in the satellite coverage.
