| In the modern warfare, spatial electromagnetic environment is more sophisticated.Electromagnetic signal is an important carrier and medium to spreading information,especially a complex battlefield, in which how to effectively manage and controlelectromagnetic frequency spectrum is the main tool of timely acquiring informationabout battle. Therefore; an analysis on spatial electromagnetic frequency spectrum is thekey to manage spatial electromagnetic frequency. With the rapid development of globalinformation, an analysis on spatial electromagnetic frequency spectrum has greatinfluence on effective management of spatial electromagnetic frequency.The article, firstly, simply shows us technologic necessity of spatialelectromagnetic frequency spectrum in the system of frequency management of thebattlefield. Based on definition of electromagnetic environmentã€electromagneticfrequency spectrum management and EMC, it analyzes the main form of signal in thebattlefield and builds signal models of radarã€electronic jamming and communicationradios. And according to the above signal forms, the article studies the signal samplingmethods and model of protecting bands; analyzes effects of space environment on EMWave Propagation; builds various Propagation model fitted for applicationsenvironment of equipment. At last, combined with mathematical models, spatialelectromagnetic frequency spectrum is analyzed by the simulation system and the finalresult verifies system designation and model in their correction. |
