UNDERWATER COMMUNICATION THROUGH A WIRELESS OPTICAL CHANNEL WITH WIDE-ANGLE RADIATION PATTERN

The article considers the issue of organizing an underwater wireless optical communication channel based on a coherent source of optical radiation with a wide-angle directional diagram of the optical transmitting system. In the course of the work, a mathematical description of the channel under study was formalized, allowing one to calculate the power flux density at the receiving point with different widths of the directional diagram approximated by a trigonometric function. Numerical modeling was performed and conclusions were made about the feasibility of using the proposed method for organizing underwater wireless optical communication.
