摘要/Abstract

摘要： 传统的多波束算法无法处理与导航信号来自同一方向的窄带干扰。针对该问题，提出了一种改进的多波束抗干扰算法，级联时频域结合的IIR格型陷波器于多波束抗干扰算法中，通过IIR格型陷波器预测并抑制窄带干扰，通过多波束形成抑制宽带干扰。这种新的算法能有效地抑制窄带和宽带干扰，提升GPS抗干扰接收机的性能。

Abstract: Traditional multi-beam algorithm cannot suppress narrowband jammer which comes from the same direction with the useful signal. To deal with those problems, an improved multi-beam anti-jam method which adds multistage IIR lattice notch filter is proposed. The narrowband jammer can be forecast and suppressed by using IIR lattice notch filter. The broadband jammer can be suppressed by multi-beam algorithm. The new method which can suppress both narrowband and broadband jammer effectively, improves the performance of the anti-jam receiver.

Key words: multi-beam anti-jam, space-time adaptive processing, IIR notch filter
