收发光轴非共面的紫外光单次散射链路模型的研究

Research of Non-Coplanar Ultraviolet Non-Line-of-Sight Single Scattering Link Model

本文在收发光轴共面的紫外光单次散射链路模型基础上,分析了收发光轴非共面时紫外光单次散射链路模型,推导了收发光轴非共面时收发光锥在空中相遇时形成的共同散射体体积的近似推导公式。分析了三种非共面的情况,第一种是收发任一端没有准确朝向对方时的链路模型,第二种是收发光轴均偏向同一侧的链路模型,第三种是收发光轴偏向不同侧情况下的链路模型。通过对三种情况下接收功率的仿真分析得到,前两种情况均可以进行通信,但接收功率不会很高,第三种情况基本不能通信,因为很难在空中形成共同散射体。

Based on ultraviolet non-line-of-sight single scattering link in coplanar model,this paper analyzed non-coplanar mode when transmitter and receiver do not face each other. Three non-coplanar cases are analyzed in this paper,one is either of transceiver does not face the other part, one is both of transceiver do not face each other. This paper mainly analyzes three non coplanar cases,the first kind is either part faces to the other part; The other two kinds are both parts do not face to each other on the same side and different sides. The simula-tion show that the former two kinds can communicate , but receiving power is not very high. The third kind can not communicate , because it is difficult to form a common scattering volume in the air.
