摘要
为了克服能见度不良及“海上光污染”等对船舶号灯可识别性的影响,提出利用甚高频(VHF)通信技术将传统号灯直线传播的灯光信号改变为借助于VHF电台进行收发;介绍了基于VHF通信的船舶号灯信号收发系统的原理、组成及编码协议;并在MATLAB环境中对该系统的收发过程进行了数字仿真,仿真效果比较理想.
In order to overcome the bad influences of the restricted visibility and "light pollution at sea" on the identification of the ship lights, a way of changing the ship lights' radiation in a beeline into transmission based on very high frequency (VHF) radio communication was put forward. The principle, composing and coding agreements of the transceiver system of the ship lights were introduced; Moreover, the digital simulation of the system's transmitting and receiving process was done in MATLAB, the simulation result was acceptable.
