Anti-jamming techniques based on digital multi-beam and robust mode control

The COMPASS Satellite Navigation System has been developing rapidly. Facing the complicated electromagnetic environment, how to effectively improve the anti-jamming capability of navigation receivers becomes more and more important for the future advanced weapon system. In this paper, we study the anti-jamming techniques based on digital multi-beam and robust mode control. The working mode is switched timely and properly according to the environment to achieve flexible beam control. Our proposed scheme improves robustness as well as time-reality and effectively decreases the power consumption while guaranteeing good anti-jamming capability. This scheme has been successfully applied in the practical project and achieved good performance.
