| 摘 要： | 拖曳天线的本地噪声决定了其接收深度及接收性能。建立了磁场天线的纵向振动模型，利用模态分析理论求得了纵向切变力作用下磁场天线的纵向振动响应，理论分析了纵向振动感应的磁致伸缩噪声产生机理，给出了磁致伸缩噪声计算公式，通过MATLAB得到了仿真结果。给出了水下接收天线电磁噪声的准确估计公式，对水下通信质量具有极大的促进作用。

| Abstract: | Electromagnetic noises of H-field antenna dominated the receiving depth and receiving quality.Longitudinal vibration model of H-field antenna was established,and the response of longitudinal vibration under longitudinal shearing force of sea water was obtained based on the theory of modal analysis.Furthermore,causation of magnetostrictive noise induced by longitudinal vibration was analyzed theoretically,and the estimation formula was given.The simulation result was obtained by the software of Matlab and compared with the experimental result.Research result gave more exact estimation formula for electromagnetic noises of underwater receiving antennas and hence will improve the quality of underwater communication greatly. |
