“日盲”紫外光定向发送与定向接收的非直视通信覆盖范围研究

Research of Coverage Model in Solar Blind UV NLOS Communication Directional Transmission and Directional Receiving

针对紫外光定向发送与定向接收的非直视(C类NLOS)通信,基于椭球坐标系,建立了通信模型,推导了通信覆盖范围的计算公式,并进行了数值分析。结果表明:紫外光接收视场角越大或收发端传输距离越长,通信节点的覆盖范围越广。

According to the directional transmission and directional receiving of non-line-of-sight （NLOS） ultraviolet communication, and based on ellipsoid coordinate system, the ultraviolet NLOS communication coverage model was built. The communication coverage calculation formula was derived and numerically analyzed. The results show that Ultraviolet receiving viewing angle and sending receiving transmission distance is larger, its communications nodes coverage is farther.
