摘要
研究了天线在随机脉动压力作用下的运动感应电磁噪声,包括:随机脉动压力谱密度计算公式的建立;电极对天线运动感应电磁噪声的产生机理与计算方法;仿真结果及分析。研究结果对于水下通信有重要的应用意义。
Electromagnetic noise plays an important role in underwater communication. Motion-induced noise of antenna under random and fluctuant pressure was studied, which included the formulae of about power spectra density of random and fluctuant pressure, the analysis and calculation of motion-induced noise of E-field antenna, and the simulation result and result discussion. The results are significant in underwater communication engineering.
