Abstract

The accuracy of underwater electric field detection determines the accuracy of underwater target identification and positioning. The original electric field will be affected when the measurement device is put in underwater electric field. The formula of underwater electric field where the three-component sensor is put in was established and the influence coefficient of the electric field was proposed by numerical simulation. The specific functional relationship of electrode length, electrode radius, Z measuring distance and influence coefficient was established. Both numerical simulation and experimental results demonstrated that underwater electric field is not affected when the three-component sensor is in the far field; the electric field effect can be neglected when the measuring distance is greater than 4 times the electrode length or the measuring distance along the axial radius is greater than 2 times the electrode radius. Research conclusions are of important significance to accuracy of actual electric field measurement.

三分量传感器对水下电场的影响系数及数值模拟

水下电场探测的精度决定着水下目标识别与定位的精度。当测量装置置于水下电场中时，会对原有的电场产生影响。建立了三分量传感器水下电场的计算公式，并通过数值模拟提出了电场的影响系数。建立了电极长度、电极半径、测Z距离与影响系数的具体函数关系。数值模拟和实验结果表明，三分量传感器处于远场时，水下电场不受影响;当测量距离大于电极长度的4倍或沿轴向半径的测量距离大于电极半径的2倍时，电场效应可以忽略不计。研究结论对实际电场测量的准确性具有重要意义。
