- 中文摘要: 眾所周知,陣列的缺陷將會使得一個適應性波束構成器的性能降低,為了解決問題,本篇論文就提出一個新架構,它可以允許信號的特性有較大的擾動而不被排除掉,比起傳統的Frost波束構成器,對陣列的缺陷,它則有較佳的效能響應。從電腦模擬,即可顯示此新架構的效用性。
- 英文摘要: It is well known that array imperfections often degrade the performance of an adaptive beamformerTo tackle this problem, this paper proposes a new structure for an adaptive beamforming system to allowgreater perturbations in the desired signal characteristics without rejection of the signal. Compared withthe conventional Frost beamformer, the new structure performs better in system response to array imper-fections. Computer simulations have illustrated the effectiveness of the proposed structure.
