Construction Method of Virtual War Field Electromagnetic Environment
Modern Defence Technology, 2009Co-Authors: Wang Jing, Li Zhi, Lai Jia-zheAbstract:War field Electromagnetic Environment has been briefly analyzed here. Aiming at the difficulty in construction of war field Electromagnetic Environment system, a method of quantitative constructing war field Electromagnetic Environment, involving the dements like broad war field, mutli-radiation source, the effect of terrain and meteorology, has been put forward here. By means of parabolic equa-tion, geographic information systems, neural network and other theories or methods, iwar field Electromagnetic Environment is established. Finally a simulation in some area of Fujian province with true geographical and meteorological circumstance has been done with this method. The simulation results are consistent with radio wave propagation' s theory, which proves the feasibility and practical application value of this method.
