Abstract
A LOS solar blind UV communication channel model is presented in the paper, which consists of three sections: propagation loss section, scattering transmission section and background noise section. LOS transmission loss model of UV channel is deduced by Lambert law and noise power calculation is also analyzed. Base on them, a practicable calculation method of signal to noise ratio (SNR) is presented, which is a bridge between system parameters and system performances such as BER and limit communication distance in analysis of UV communication. Transmission loss and SNR of LOS are measured in outdoor experiments. The experiment shows that SNR calculation data agree with the experimental results quite well. The calculation also shows that the limit communication distance of LOS can achieve 7kms with the UV sensor at present.
