摘要:

宽带恒定束宽波束形成可实现宽带信号带宽内波束图主瓣宽度恒定,在传统的抽头线延迟阵列中,恒定束宽波束形成可设计为凸优化的方法,该方法可扩展到阵列延迟线阵列宽带波束形成,文中提出一种可用于最差环境中导向向量失配条件下,基于SRV约束的恒定束宽波束形成方法,Matlab仿真实验表明了算法的正确性和有效性。

关键词: 波束形成, 恒定束宽, 最差环境, SRV约束, MVDR

Abstract:

Beamforming for broadband constant beamwidth can achieve constant main lobe width in the bandwidth of broadband signal.In traditional tapped delay-line array (TDL),constant beamwidth beamforming can be designed as a convex optimization method.It can be extended to broadband beamforming system with sensor delay-lines.In this paper,a constant beamwidth beamforming is proposed based on SRV constraint in steering vector mismatching of worst-case environment.Matlab simulation validates the effectiveness of the algorithm.

Key words: beamforming;constant beamwidth;worst-case environment;SRV constraint;MVDR
