Multi-beam Anti-jamming Technique in Satellite Navigation Receiver

抗干扰是卫星导航接收机中一项重要的技术。提出了一种卫星导航接收机中的新型多波束抗干扰方法,该方法能够较好地兼顾零陷深度与卫星信号增益的矛盾,达到抑制干扰的同时增强卫星信号强度的目的。通过大量仿真实验分析了波束数目、波束分配方式以及波束指向偏差对抗干扰性能的影响。仿真结果和性能分析验证了该方法的有效性和可行性。

Antijamming is an important technique in satellite navigation receiver. A no vel antijamming method based on the multibeam in the satellite navigation receiver is pro posed in this paper. This method is able to solute the conflict between the depth of the zero trappers and the gain of the satellite signals. A lot of simulation experiments are also given to verify the performance of the method in different beam number, beam distribution mode and the tolerance of beam pointing error, and the simulation results show that the method proposed is efficient and feasible.
