摘要

在本文中，我们提出了一种利用空间响应变化(SRV)的宽带波束形成方法，该方法被定义为测量阵列在期望频带内空间响应的波动。通过将SRV应用于正则化项，我们在期望的频带内获得了小于1度的高质量主波束宽度变化。在设计实验中，我们证明了该方法优于现有方法。

A study on the broadband beam pattern synthesis using spatial response variation

In this paper, we propose a broadband beamforming method using the Spatial Response Variation (SRV) which is defined to measure the fluctuation of the array spatial response within the desired frequency band. By applying the SRV to regularization term, we achieve a good quality main beam width variation less than 1 degree within the desired frequency band. In design experiments, we show that the proposed method is better than the existing method.
