摘要
分析了海洋与陆地导电特性及地形对空间波和地表波传播的影响，讨论了短波、超短波频段的噪声特性．对海洋遥测数传系统进行了设计，给出了海洋遥测装置应使用的载频和码元速率．对海洋遥测接收机灵敏度及采用３次重发、３取２大数判决的差错率进行了分析计算．
Effects of the electrical conductance characteristics as well as of the terrain features, both marine and over land, upon the propagation of groundwave and skywave are analyzed. Carrier-frequency range and code ratio suitable for a marine telemetering system is presented. The results of calculation for the sensitivity of telemetering receiver and its error probability are given, taking 2 identical bits from 3 corresponding bits received, with 3 fold retransmission.
