Abstract

The communication ways nowadays has highly developed, but because of its using limitation, the application is restricted, especially under the emergency situations. Using infrared laser non line of sight atmosphere scattering can solve the difficult problem effectively, and achieve the function of “minimizing communication support”. The article try to study the 1.06μm laser atmosphere scattering communication, first, we introduce the laser scattering communication technique and principle, and then describe the system composition and work route. In the way of building the laser atmosphere scattering communication system math model, the article analyze the relations between the laser receiving rate and the following elements: laser beam emission angle, receiving field vision, detector sensitivity, emission inclination angle, receiver inclination, atmosphere attenuation, laser launch rate, and communication distance. Based on the simulations, the field experiment showed, that the 1.06μm infrared laser signals transmission has the probability to achieve the long distance atmosphere scattering communication under certain atmosphere conditions.
