摘　　要：传统的反辐射雷达导引头天线通常具有较宽的波束,且具有固定的波束方向图,这就必然导致不同空域的目标辐射信号和干扰信号同时进入导引头接收系统,严重影响导引头的测向性能,无法适应未来复杂电磁环境下工作的需要。为此,提出一种基于自适应数字波束形成技术的主动抗干扰方法,并研究该方法在导引头系统中应用的可行性。仿真结果表明,采用该方法能够实现干扰抑制,所得结果对自适应波束形成技术在被动导引头系统中的应用具有启发意义。For conventional anti-radiation seeker with larger beamwidth and fixed antenna direction,the target signal and jamming from multi-sources will enter seeker＇s receiver simultaneously.Therefor direction finding performance of seeker is degraded seriously.It is not well matched with complex electromagnetic environment in future.For this purpose,an active anti-jamming method based on adaptive beamforming technique is proposed,and its feasibility in seeker is studied.The simulation results show that the method presented can realize jamming suppressing.The results obtained are suggestive for applying adaptive digital beamforming to seeker.
