Aircraft RF Compatibility Numerical Simulation Technology Research

As the name implies,electromagnetic compatibility of aircraft is a study of all kinds of electronic devices worked in Aircraft can be safely co-exist.Electromagnetic compatibility is all kinds of equipment and power system can work well under the coexistence of electromagnetic environment,and will not affect other electrical equipment in the form of electromagnetic disturbance.This topic focuses on the study of airborne antenna numerical simulation technology under the radio frequency spectrum.Simulation analysis of different algorithm and frequency,forming a set of RF compatibility simulation process for typical airborne antennas.First of all,optimize two different types of airborne antennas,so that they can good work in the low frequency to high frequency.Secondly,based on the research of electromagnetic simulation algorithm,deeply research the principle and applicable conditions of FIT,FEM and SBR.For different frequency of the antenna,combined with the advantages and disadvantages of different algorithms,using CST software simulation to find out what works for different antenna is presented,including the comparison of the simulation error,the duration of the simulation and so on.Then,comparison and analysis different simulation results of the algorithm.Finally,based on the analysis of the results,formed a set of applicable to typical airborne antenna RF compatibility simulation process,which provides a reference for the RF compatibility simulation of airborne antennas.
