Improved eigenfilter-based time-domain wideband beamforming

  • 摘要: 为实现基于本征滤波宽带波束形成的频率不变性和零陷设计,提出一种改进的方法.基于最大能量阵列代价函数和主极大方向阵列响应线性约束构造的优化模型,将阵列空间响应偏差整合入代价函数,从而实现频率不变性的设计;提出了两种零陷设计的方法,将扩展旁瓣能量整合入代价函数和添加干扰方向阵列响应线性约束,构造两个新的约束优化模型,最后均由本征滤波的方法求解.仿真实验表明,该方法能在通带范围内实现指定角度范围内阵列响应的频率不变性和零陷效果,同时具有低旁瓣增益,验证了本文算法的有效性和良好性能.
