Abstract

An analytical model of non-line-of-sight (NLOS) single-scatter propagation is presented that has no integral form and is intended for performance analysis and system design of NLOS UV communication. Based on isotropic scattering and a continuous wave transmitter, the analytical model is verified by the current NLOS single-scatter propagation model, with consistent results. Several rules concerning NLOS UV communication are put forward on the basis of this analytical model, which are shown as follows: on condition that the minimum single-scatter optical depth is less than 0.1, the path loss factor should be 1; to maintain the NLOS UV communication link, the transmitter needs to radiate neither a continuous wave nor a huge pulse but a low-power wave whose duration is approximately the duration of impulse response; the “best” extinction coefficient is approximately the inverse ratio of the efficient single-scatter range; on condition that the radiation intensity of the transmitter is fixed, the half field of views (FOVs) are positive factors, while the elevation angles are negative factors; on condition that the power of the transmitter is fixed, the conclusions mentioned above remain valid with the exception that the half FOV of the transmitter is a negative factor. These rules also apply to anisotropic scattering.
