Exploring the practical aspects of atmospheric optical communication and light detection and ranging (LIDAR), this book details the role of atmospheric structures in propagation phenomena that influence the transmission of optical signals through perturbed atmospheric communication channels. It examines numerous situations in over-the-terrain atmospheric communication channels-including the effects of natural phenomena-and the corresponding features (turbulences and hydrometeors) on optical ray propagation.

Exploring the practical aspects of atmospheric optical communication and light detection and ranging (LIDAR), this book details the role of atmospheric structures in propagation phenomena that influence the transmission of optical signals through perturbed atmospheric communication channels. It examines numerous situations in over-the-terrain atmospheric communication channels-including the effects of natural phenomena-and the corresponding features (turbulences and hydrometeors) on optical ray propagation. Bridging the gap between the parameters of optical communication links and signal information data streams, this concise reference addresses line-of-sight (LOS) as well as obstructive non-line-of-sight (NLOS) propagation conditions.
