A universal non-line-of-sight (NLOS) ultraviolet single-scatter propagation model in noncoplanar geometry is proposed to generalize an existing restricted analytical model. This generalized model considers that the transmitter and the receiver cone axes lie in the same plane or different planes, where they can be pointed in arbitrary directions. The model is verified by extensive simulations, showing that the proposed model is consistent with the original NLOS single-scatter propagation model and the Monte Carlo model. The path loss performance is further investigated in terms of different noncoplanar geometric settings and path loss dependence is also analyzed for different factors, including scattering volume size, relative position between the scattering volume and the transceiver, and radiation intensity of the transmitter.
提出了一种通用的非共面几何中的非视距（NLOS）紫外单散射传播模型，以推广现有的受限分析模型。该广义模型考虑发射机和接收机圆锥轴位于同一平面或不同平面，且它们可以指向任意方向。通过大量仿真对该模型进行了验证，结果表明所提出的模型与原始的NLOS单散射传播模型和蒙特卡罗模型一致。针对不同的非共面几何设置进一步研究了路径损耗性能，并分析了不同因素（包括散射体体积大小、散射体与收发机之间的相对位置以及发射机的辐射强度）对路径损耗的影响。
