为了构建工作在kHz频段的水下定位系统，利用我们提出的导电介质的伪尺度模型，测量了盐水中两个铠装偶极天线之间的传输系数。发射天线正好放置在空气和盐水区域之间的界面下方，并且接收天线在盐水区域中三维移动。所得到的距离特性受到直达波以及侧向波的影响，所述侧向波向上传播到表面上的点，沿着空气区域中的表面，并且向下传播到接收端。
To construct the underwater positioning system operated in the kHz band, we measure the transmission coefficient between two sheathed dipole antennas in the salt water using the pseudo scale model for the conducting medium, which is proposed by us. The transmitting antenna is placed just beneath the interface between air and salt-water regions and the receiving antenna is three-dimensionally moved in the salt-water region. The resulting distance characteristic is affected by the direct wave as well as the lateral wave which travels up to a point on the surface, along the surface in the air region, and down to the receiving
