The paper introduces a new method for prediction of electromagnetic compatibility in the power system, and use the Electromagnetic simulation software ATP. By comparing the actual test results to the simulation results, it is proved that electromagnetic transient simulation is reliable and effective. It also introduces the Gray prediction theory to predict the next Electromagnetic Interference (EMI) of the substation. It is high practical to research and analyze the substation electromagnetic compatibility, and feasible to use the Gray prediction theory with multivariable for the model EMI prediction analysis.

Europe, the United States and China have conducted a lot of research on the detection and localization of underwater target. The United States, the typical representative among Europe and America, pays much attention to marine research and has a profound foundation. In China, Harbin Engineering University, Institute of Acoustics of Chinese Academy of Sciences and Northwestern Polytechnical University also have done a lot of research on target detection and localization. Overall, the United States of America and other developed countries temporarily precede China in underwater target detection and localization.
