ABSTRACT摘要【Extract Key Contents】

1. This doctoral dissertation discusses recent advancements in multidimensional (MD) space-time signal processing algorithms and circuits for electronically scanned smart antenna array receive mode beamforming.（这篇博士论文探讨了多维空时信号处理以及接收模式波束形成 电子扫描智能天线 电路 的最新进展）【老外写文章真的是~~~】
2. The proposed MD signal processing models exploit planar-resonant properties of MD passive prototype networks to design MD space-time fi lters with in finite impulse response(IIR) at guaranteed lter stability.(为保证滤波器的稳定性，文中提出的MD(多维)信号处理模型 利用MD 被动原型网络的平面谐振特性 设计无限脉冲响应MD空时滤波器        %保证了滤波器的稳定性%)
3. The beamforming problem is analyzed in a MD signal processing perspective to proposed novel MD signal processing models and massively parallel digital circuits to support multi-beam linear aperture arrays.（为提出新型多维信号处理模型和大规模并行数字电路来支持多光束线性孔径阵列，我们从多维信号处理的角度分析了波束形成的问题） 
4. Closed-form design equations are provided, which relate MD filter design parameters to beam personalities in the array pattern. A quantitative comparison of three-dimensional(3-D) IIR cone filters with conventional phased array beamformers is performed to
   show that the 3-D IIR cone fi lters provide frequency independent beam selectivity at an order of magnitude lower multiplier circuit complexity in a typical digital hardware implementation（本文展示了封闭形式的设计公式，其将多维（MD）滤波器设计参数与阵列波瓣中波束特性联系起来。通过对三维无限脉冲响应锥形滤波器与传统相控阵波束形成器的定量对比，表明在一个典型的数字硬件中三维无限脉冲响应锥形滤波器 可以以复杂性数量级更低的乘法器电路 提供频率独立波束选择）
