摘　　要：传统空时自适应处理(STAP)算法不能抑制和导航信号同一方向的窄带干扰并且输出信干噪比不理想。针对此问题,本文提出了一种结合加权波束的改进STAP抗干扰算法。这种新的算法能有效地抑制窄带和宽带干扰,并提升了输出信干噪比(SINR)。Traditional space-time adaptive processing algorithm cannot suppress narrowband jammer which come from the same direction with the useful signal and have a bad SINR.Focus on those problems,an improved STAP anti-jam method which combine weighted beam-forming was proposed.The new method can suppress both narrowband and broadband jammer effectively,which can also improve the SINR.
