Optimal visualization design for electromagnetic environment situation of the sea

Due to the ubiquity of wireless communication systems, electromagnetic environment over the sea has become more and more complex, which leads to the urgent demand on the cognition of electromagnetic environment and the accurate illustration of electromagnetic situation. In this paper, an optimal methodology to calculate the electromagnetic spatial energy distribution over the sea has been proposed. Based on the computation results, the electromagnetic environment situation map has been generated to illustrate the electromagnetic energy distribution over the sea under observation. According to the real-time information of equipment provided by database, the visualization work can be accomplished promptly to provide valuable information for potential interference discovery and decision making over the sea. In addition, an approach for spectrum management and distribution has also been proposed to discover vacant frequency band, which can improve the efficiency of spectrum utilization.
