| 摘 要： | 通过对极低频拖曳全向接收天线运动感应噪声产生原理的研究,得出了潜艇电极对拖曳天线和磁场天线的运动感应噪声功率谱的表达式,详细指出了天线灵敏度、电缆特性、地磁场等关键因素在影响运动感应噪声方面所起的作用,探讨了减小运动感应噪声的方法,并与实验测得的噪声电压进行比较证实了上述理论。

| Abstract: | The theory for motion-induced noise generation of the extremely low frequency omni-directional anten-na is studied, and formulae for the submarine towed electrode-pair antenna and H-field antenna are represented in the form of the motion-induced noise voltage power spectrum. The effeets of various contributing factors such as antenna sensitivity profile, cable properties and geomagnetic field are indicated. The approach to reducing the noise is dicussed in detail. Finally, the theory is supported by the experimental results. |
