摘要
超长波天线工作在导电媒质中,与传统天线的工作环境有很大的不同。研究了导电媒质中的超长波电磁波传播特性,分析了海面与空气交界处的电磁波传播规律,详细地推导了海面下超长波电磁波的各项场分量表达式,给出了天线的方向函数、有效长度、输入阻抗、等效噪声场等重要参数,为深入分析研究超长波接收天线提供了基础的理论支持。
Super long wave antenna runs in an electric medium, and the work entironment differs with traditional antennas. Propagation characters in electric medium of super long wave electromagnetic wave was studied, and the propagation law in the border between seawater and air was analysed. Some important parameters of super long wave antenna, such as pattern, effective length, input resis- tance and effective noise field, were deduced ,which makes theoretic support for deeply studying super long wave receive antennas.
