摘要

Unmanned aerial vehicles (UAVs) are gaining popularity for diverse applications such as precision agriculture, delivery services, disaster management, commercial use, environmental monitoring, search and rescue operations, etc. UAVs are designed to transfer significant amounts of data originating from high-resolution cameras and sensors. Most UAVs are operated using conventional RF communication, which is constrained to limited data rates, high license costs, security concerns etc. Free space optics (FSO) communication shows a prompting approach for high-speed data transfer with unlicensed bandwidth and low operational cost. Besides the advantages, UAV-FSO is constrained to atmospheric attenuation and strict line-of-sight conditions. This paper analyzes the performance of the UAV-FSO system over atmospheric turbulence (AT), pointing errors (PEs), and angle of arrival (AoA). A more generalized radial distribution is considered for the PEs to include boresight and jitter effect. A closed-form outage analysis is derived from the combined channel conditions with generalized PEs and analytical results are compared with simulation and existing methods.
