Recent measurements and developments in optical propagation in the air and in the sea have opened the door to applications of significant importance to military systems. As an example, transmission measurements in the marine boundary layer have demonstrated that light beams are strongly scattered in the forward direction by hydrometeors as a result, communication links may be possible beyond line of sight. Another example is improved modeling of the upper atmosphere and related propagation effects, which allows high altitude sensing systems to discriminate between target and background radiance. Such phenomena and others peculiar to atmosphere and marine environments offer unique possibilities to communicate between space based and submerged platforms as well as pointing the way to remote observations. The resultant applications to communication and surveillance are of great interest to the military. This meeting reviewed these propagation phenomena to establish their limitations on transmitting and receiving equipment and bring out military implications and applications. Author
