UV Communication System Design with Lower Delay Time

UV atmospheric transmission theory and the Non-Line of Sight single scattering channel model were introduced.According to the model,the transmission loss caused by atmospheric channel under different structure design was qualitatively analyzed,and the attenuation under different parameters was quantitatively simulated.Experimental results show that delay time increase with increasing transmission distance,launching elevation and receiving elevation,and influence degree of launching elevation is more serious than receiving elevation;it decreases with increasing beam divergence angle and increasing field angle.To decrease delay time of communication system,the design of UV communication system should decrease launching elevation and receiving elevation,and increase beam divergence angle and field angle.
