This paper presents a brief introduction to anti-jamming technology and the current status of multi-satellite and multi-beam application, and then proposes a new digital multi-beam anti-jamming receiver implementation method. This method uses inertial device data (heading, pitch angle, and roll angle) to determine the single-constrained steering vector and further derives a digital multi-beam improved acquisition algorithm with a space-time adaptive processing structure. Simulation result shows that the improved acquisition algorithm can fully utilize multi-beam data, stabilize carrier phase, and achieve stronger spatial gain and higher spatial resolution.
