中文摘要:
      利用波导中的声场匹配与自由空间中的阵列处理的相似性,从自由空间的阵列零点方法出发推导一种适用于波导中垂直阵列声场匹配的抑制固定干扰的方法。通过声场模型预报已知空间位置干扰的声传播特征,形成空间矢量。在保持期望点增益的前提下,约束干扰点邻域增益,得到垂直阵列的零点指向干扰的阵列权向量。
英文摘要:
      Taking advantages of the similarity between the matched acoustic field in the wave-guide and the array processing in the free space,a new method of suppressing the fixed interference for vertical array MFP in the wave-guide is obtained by the array zero point in the free space.The space vector can be got by forecasting the sound propagation character with the interference whose location is known by the acoustic field model.The array weighting vector of the interference in the direction of the zero points of the vertical array can be given as keeping the anticipant point gain and restricting the interference point neighborhood gain.
