摘　　要：紫外光由于具有日盲特点而使其在通信方面有着特殊的的必要性及优越性,紫外光的调制与接收是紫外光通信和其他常用通信方式的主要区别点;介绍了紫外光通信系统的构成原理并着重讲解了紫外光通信系统中的关键装置———语音编码-解码和紫外光的调制与接收;提出了一种较好的紫外光通迅模式,为现代作战单元无线指控数据链和指挥所无线局域网的短距离紫外光通信的进一步发展提供了借鉴。The ultraviolet communication system has special necessity and superiority because of the day--blind characteristics of ultraviolet, The modulation and receiving of ultraviolet are the main difference between the ultraviolet communication system and other communication systems. The composition principle of the ultraviolet communication system and emphatically the key device in the system the pronunciation codedecodes and the modulation of the ultraviolet are introduced. A kind of better communication mode based on ultraviolet ray is proposed and a reference for the further development of the ultraviolet communication system of modern combat unit wireless indictment data chain and wireless LAN of command post is offered.
