GMDSS课后题(题库+答案)上海海事大学

1.试设计A3海区国际航行船舶双套无线电通信设备的配备要求。

2.哪些是不同航行海区船舶都要配备的GMDSS设备？所述它们的主要功能。

I甚高频无线电话（VHF）：用来实现船岸间或船舶间近距离通信，同时通过海岸/港口VHF 电台的转接实现船舶电台与陆地公众网用户间的电话通信。

II奈伏泰斯接收机（NA VTEX）：储存、记忆功能；自动接收和打印功能；自诊断功能III救生艇筏双向甚高频无线电话（TWO-WAY VHF）主要用于救生艇筏之间、救生艇筏与船舶之间、以及救生艇筏与救助单位之间的现场通信。

IV搜救雷达应答器（SART）：可以根据SART发出声响变化来判断救助船是否到来、或越来越近、或估计有多艘船舶前来救援；同时还具有视觉指示功能。

3.无线电信号的空间传播主要方式有哪几种？各有什么特点？主要方式：直射（视距）传播、地波（绕射）传播、天波的折射和反射传播及散射传播特点：直射传播：收和发两端点（天线）处在直视范围内，能互相看得见。

视距传播距离一般只有几十公里，主要用于短波和微波。

地波传播：地波沿地面传播时会受到衰减，波长越短，衰减越大。

不受气候的影响，传播相对比较稳定。

适用于长波和超长波和极长波。

天波传播：通信距离远，传播不稳定，存在通信静区，适用于中短波。

4.试解释天波电离层传播的多径效应和衰落现象，通信静区和盲区。

多径效应：由于电波从发射点到接收点的传播并非只经过一条路径，往往是既有天波又有地波，而且天波也因反射的电离层不同和反射的次数不同，传播的路径也不同。

因此到达接收地的电波场强是各条路径电波的矢量和。

衰落现象：因漫射波的传播路经不同，而随电离层的反射高度而变动，故各条路径来的信号不能保持固定的相位差是叠加后的信号幅度发生变化。

通信静区：在短波波段，地面波随距离的增加衰减很快，地波能到达最远距离为D1，当一定频率发射的电波以一定的入射角向电离层投射式随入射角不同而到达点的位置也不同，到达最近距离为D2。
