　　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。

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 fil-ter 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 effec-tively, improves the performance of the anti-jam receiver.
