Modeling Of Space Electromagnetic Information And Analysis Of Frequency Conflict

The development of electronic information technology makes the battlefieldenvironment become more complex. Electromagnetic environment, as the importantfeature of battlefield, analysis of the structure and characteristic is very important forunderstanding the battlefield environment. Information weapon is the sender ofelectromagnetic signal, they are densely distributed in space and overlaped in frequency,resulting in the spectrum crowded, and the battlefield electromagnetic environmentbecomes complex and unpredictable. Therefore, analysis of the frequency conflictbetween equipments helps us manage the electromagnetic spectrum and analysis thebattlefield electromagnetic environment better.Firstly, the development and research status of electromagnetic environment issummarized by the paper; the necessity of frequency conflict research betweenequipment is analyzed. Secondly, according to the type of battlefield equipment, modelhas been established, and genarate corresponding signal combined with differentequipment type, equipment parameters, communication environment and so on;Analyze the frequency domain characteristics of signal, calculate the power in specificreceiving frequency band of signal, calculate the electromagnetic strength of equipmentin a certain airspace; judge the interference situation of equipment in a specific workingfrequency band, extract conflict frequency band and conflict time. Finally, the spaceelectromagnetic information modeling and the analysis of frequency conflict are tested;the simulation results show the correctness of the model and algorithm.
