Naval Blue-Green Single-Pulse Downlink Propagation Model

This technical report describes the official Navy model for signal and noise characteristics of a single blue-green optical pulse propagated from a satellite laser source to a submerged receiver in all weather conditions. A mathematical model is developed in two groups: the signal group relates the instantaneous received optical signal power, while, the noise group relates the total noise equivalent optical power to the noise source. Both groups of the model account for propagation path and receiver characteristics; and, they allow calculation of the signal-to-noise ratio for any blue-green single-pulse downlink from a satellite laser source to a submerged receiver. The relative technical uncertainty in accuracy of both equation groups has also been included.
