摘要
自适应波束形成理论是"自适应阵列信号处理"课程教学中的难点和重点内容。本文以最小方差无失真波束形成(MVDR)和范数约束Capon波束形成(NCCB)为例,详细介绍了CVX凸优化工具箱在自适应波束形成器设计中的应用,并对不同快拍数情况下波束形成器的性能进行了比较与分析。实践表明,将CVX工具箱引入到自适应波束形成实验中,可以使该理论教学更加直观和易于理解。
The theory of adaptive beamforming is one of the difficult and important contents in the teaching of Adaptive Array Signal Processing course. This paper takes the minimum variance distortionless response beamforming（ MVDR） and norm constrained Capon beamforming（ NCCB） as examples,and introduces the application of CVX convex optimization toolbox in the design of adaptive beamforming. The performance of beamformers with different number of snapshots is compared and analyzed. It is indicated that the theory of adaptive beamforming can be more intuitively and easily understood by introducing the CVX toolbox into practice teaching.
