摘要
首先分析了水下电流场通信的原理,给出了电极对天线接收信号电压的表达式。针对水下通信距离近的问题提出了增加通信距离的方法,包括定向天线法、介质盘法和改变传感器的形状。根据以上方法的要求制作了不同类型的电极对天线,并在实验池中对上述方法进行试验测试分析,测试结果验证了以上方法的可行性。
First,the paper has analyzed the principle of underwater current field and provided the received voltage of Efield sensor.To the question of short communication distance,some methods of increasing communication distance are raised,including directional antenna,medium plate and changing sensor＇s shape.Different kinds of sensors are made depending on above methods,and testified in experimental pool.The result tesfifies the possibility of above methods.
