Abstract


In today's world , as national defense, business needs , transportation and other aspects of the increasing demand , highlighting the growing importance of ship , its functional requirements have become increasingly complex . In the modern warship , due to the complete information and communications , weapons control , navigation, detection , and many other functions , so to carry a large number of electronic devices. Consequences resulting electromagnetic environment is worsening ship , in order to solve the electronic devices of electromagnetic interference (EMI) problems, can be used for shipboard electronic equipment to optimize the layout of the transmitting antenna method . This article from the ship on the analysis of electromagnetic environment aspects, first introduced the calculation of electromagnetic field theory and far, near-field principle of classification. Describes the form of electromagnetic integral equation and its solution method to analyze the advantages and disadvantages of different methods and results between errors and ultimately multilevel fast multi -level sub- law as a solution of electromagnetic integral equation approach. Subsequently elaborated coupling , electromagnetic near-field intensity and pattern distortion three parameters of the physical meaning and optimize the layout of the antenna . But also through different frequency compared their variation . Frequency of final consideration factors to determine the degree of coupling , the near field intensity pattern distortion and frequency as the optimal layout of the antenna elements . Analysis, a mathematical model of the control condition , and optimize the layout obtained by calculating the position coordinates and the corresponding optimization of the operating frequency of the antenna arrangement as the final result. During which time parameters calculated using the famous FEKO software to calculate. In the design process , in order to be able to consider a variety of circumstances ship antenna layout mutual influence and simplify design, using Matlab call EDITFEKO modeling, computational methods , and the results processed using Matlab to the optimal layout the operating frequency of the antenna and associated coordinates.
