摘要

针对阵列信号中部分自适应信号处理问题,提出了一种新的基于平滑阵列的降维方法. 该方法将全阵列平滑处理,通过分割成相互重叠的子阵达到降维的目的. 该波束形成器使用了两级加权的结构. 根据方向图相乘原理,天线方向图是两级加权矢量独立产生的方向图的乘积,此波束形成器可以等效为一种空域滤波器的级联形式. 通过大量的计算机仿真验证了此方法的有效性和优越性.

Abstract

A new dimension-reduction method based on subarray architecture is proposed for solving problems in partially adaptive array processing. This method uses the smoothing array algorithm and divides the whole array into the overlapping subarrays to actualize dimension-reduction. This beamformer has a two hierarchical weighted structure. Based on the principle of the antenna map multiplication, this new beamformer is equivalent to the serial form of two spatial filter. Finally, simulation demonstrates the validity and superiority of the new algorithm.
