摘要
水下磁场与电场天线横向振动诱发的电磁噪声在长波通信电磁噪声中占主导地位,直接影响收信深度和通信质量.针对此问题,建立了天线的横向振动模型,导出了天线的随机振动响应,分析了磁场与电场天线横向振动诱发电磁噪声的产生机理及特性,并给出电磁噪声的仿真结果和分析.研究结果为拖曳天线设计和水下电磁噪声深入研究提供了理论基础.
Transverse-vibration-induced electromagnetic(EM)noise of underwater Hfield and E-field antenna plays the most important role in EM noises for long wave communication,which has significant influence on the receiving depth and communication quality.The transverse vibration model of towed antenna is established and the response of transverse stochastic vibration is induced.Causation mechanism and characteristic of transverse-vibration-induced EM noise for H-field and E-field antenna is analyzed.Furthermore,simulation results and analysis of EM noise are given.The results provides powerful theoretical basis for enhancing the design level of towed antenna and further researches of underwater EM noises.
