摘要
光散射通信技术是当前短波光学研究的热点。介绍了目前常用的基于日盲区紫外光散射通信系统的工作原理,着重从接收的角度分析了通信系统的光学干扰机理,以及常见光学干扰源(太阳、路灯等)的光谱特性,提出相应的对抗措施。研究结果表明,太阳光和路灯对基于碲化铯阴极紫外通信系统的影响较大,通过光学方法、电路滤波技术或新型探测器技术可较好地改善系统性能。
It is a hot topic in research of shortwave optics to study light-scattering-communication technology. In this paper, the principle of light-scattering-communication system based on solar-blind ultraviolet at present is described in detail. Then the mechanism analysis of optical jamming for communication system is discussed because of detecting, according to the spectroscopic analysis of optical jamming source （sun, street-lamp and so on）. And the corresponding countermeasures needed are advanced here. The street-lamp and sunlight have a biggish effect on ultraviolet communication system using Cs-Te, and preferable system can be brought by the technology of optical method, circuit-filtering as well as new detecting instruments.
