Modeling of ultraviolet scattering propagation and its applicability analysis

Area of Science:

• Optics and Photonics
• Wireless Communications
• Remote Sensing

Background:

• Existing ultraviolet (UV) single scattering models lack transceiver geometry considerations, leading to inaccuracies in UV communication path loss calculations, especially for short-range scenarios.
• General UV communication requires models applicable to transceivers with fields of view above ground.

Purpose of the Study:

• To propose a novel single scattering model for UV communication that accounts for transceiver geometry.
• To address the limitations of existing models in accurately predicting path loss in ground-based UV communication systems.
• To provide a more accurate method for calculating UV channel path loss.

Main Methods:

• Developed a new single scattering model incorporating transceiver geometry for UV communication.
• Utilized the number of intersections between special rays and a transceiver cone to classify communication scenarios for analysis.
• Compared model predictions with Monte Carlo simulations to validate accuracy.

Main Results:

• The proposed model demonstrates improved accuracy for UV communication path loss, particularly when transceiver geometry is considered.
• Analysis revealed that the single scattering approximation becomes less accurate as transceiver elevation angles increase, even at short ranges.
• Significant path loss differences emerge between the proposed model and Monte Carlo simulations under specific elevation angle conditions.

Conclusions:

• The developed single scattering model offers a more accurate approach to calculating UV channel path loss.
• The findings highlight the limitations of single scattering approximations in certain UV communication scenarios, particularly at higher elevation angles.
• This research provides valuable guidelines for the design and optimization of experimental UV communication systems.
