摘要
电场信号是船舶一种重要的水下目标信号特征,为了对其特性进行深入研究,设计完成了一套移动台站式水下轴频电场测量系统,并使用该系统对海洋环境电场和船舶轴频电场进行了测量和分析。结果表明:该系统能够完成对水下环境电场和船舶轴频电场的测量工作,船舶水下轴频电场在频域上有明显的线谱特征,适合作为对海上船只进行远程探测的信号源。
The electric field signal is important in seawater. In order to make the characteristics of e- lectric field clear, a measurement system was made up and a maritime test was carried out in a certain area. Based on the signal got by the equipment, maritime tests show that the system can measure elec- tric field under water. The shaft-rate electric field shows evident line spectrum feature in the frequency domain, so it is suitable to be a signal source of detection to ship in long-distance.
