RF Lens Antenna Array-Based One-Shot Coarse Pointing for Hybrid RF/FSO Communications
Because of its high directivity, free-space optical (FSO) communication offers a number of advantages. It can, however, give rise to major system difficulties concerning alignment between two terminals. During the link-acquisition step (a.k.a. coarse pointing), a ground station can be prevented from...

| description | Because of its high directivity, free-space optical (FSO) communication
offers a number of advantages. It can, however, give rise to major system
difficulties concerning alignment between two terminals. During the
link-acquisition step (a.k.a. coarse pointing), a ground station can be
prevented from acquiring optical links due to pointing errors and insufficient
information about unmanned aerial vehicle locations. We propose, in this
letter, a radio-frequency (RF) lens antenna array to increase the performance
of coarse pointing in hybrid RF/FSO communications. The proposed algorithm
using a novel closed-form angle estimator, compared to conventional methods,
reduces the minimum outage probability by over a thousand times. |
