摘要
传统雷达技术体制和干扰抑制方法难以对抗集群干扰的根本原因在于缺乏足够的自由度和精准的波束赋形能力.为此,将阵列体制与波束形成技术相结合,抓住其具备高维自由度这一根本优势,基于几何解析、权矢量投影等理论,提出精准控零、主瓣保形、区域控制的波束赋形方法.仿真结果表明,本文所提方法解决了传统自适应波束形成的主瓣畸变、零陷互耦、数据依赖等问题.
The fundamental reason why traditional radar technology systems and interference suppression methods have difficulty in countering cluster interference is the lack of sufficient degree of freedom and accurate beamforming capability.To this end,by combining the array system with beamforming technology and seizing its fundamental advantage of high dimensional freedom,this paper is based on geometric analysis,weight vector projection and other theories to propose a beamforming method with precise zero control,main lobe conformal and area control.Simulation results show that the proposed method solves the problems such as main lobe distortion,nulling mutual coupling and data dependence in traditional adaptive beamforming.
