摘要(Abstract):
当干扰机相对雷达阵列天线高速移动时，干扰呈现非平稳特性，使用传统抗干扰算法对其抑制会出现零陷与干扰失配现象，进而导致抗干扰失效。针对此问题，提出一种基于协方差矩阵锥化(CMT)的多维域干扰抑制方法，能在极化、空、时多维域实现精确的信干分离。首先，通过在极化、空间多维域添加服从Laplace分布的虚拟干扰簇来模拟动态干扰波达方向(DOA)扰动的变化。然后，构造锥化矩阵并对原始协方差矩阵锥化，进而结合最小方差无失真响应(MVDR)波束形成器实现零陷展宽。模拟实验从抗干扰零陷、输出性能、匹配滤波结果3方面验证了所提方法在干扰DOA扰动下的可行性。此外，所提方法对来自主瓣的干扰同样能够有效抑制。
