Cloud Modeling Requirements of Pulsed Laser Communications Systems
Abstract
Pulsed laser communication systems have been proposed which work through all types of clouds. Predicting the performance of such systems requires a knowledge of the statistics of the spatial, angular and temporal spreading of pulses by clouds. Current models are particularly weak in predicting pulse transmission/reflection when the transmitter is near the horizon with respect to the receiver. A database consisting of the probability of cloud pattern types has been developed to be used with a database of cloud pattern properties. Together these two databases are used to predict system performance statistics for operational scenarios. In the future, real-time operational planning for message delivery will require short term predictions of cloud fields and their effects on performance. Models of reflection of pulses from clouds, as well as transmission through them are needed to make accurate evaluations of the probability of interception and disclosure of receiver or transmitter position.
