| 摘 要： | 在潜艇拖曳电缆的电极对天线中附加磁场天线是消除接收盲区、实现潜艇通信全向接收的重要手段。拖曳磁场天线的噪声主要有热噪声、运动感应噪声、磁致伸缩噪声和巴克好森噪声四种，分析并采取措施降低这些噪声是实现全向天线的关键。针对运动感应噪声的原理进行了分析，得出了噪声ENF与天线机械性能、天线灵敏度之间的关系，并由此提出了降低该噪声的途径。

| Abstract: | Attaching H - Field antenna to a towed marine cable is an important method for eliminating blind - region and achieving all -direction marine communication. The Mainly- Effected Noises of towed H- Field antenna include Thermal Noise, Motion- Induced Noise,Magnetostrictive Noise and Baxkhausen No;se.Analysing and reducing these noise is the key point to make all- direction antennas. This text analyzes the reason of Motion - Induced Noise, finds the relationship between noise ENF and antenna mectmaism performance , antenna sensitivity,finally provide means to reduce this noise. |
