| 摘 要： | 建立了微波脉冲在建筑物内传播、反射及透射过程的3维仿真模型，提取了空间电场时域最大值进行统计分析。分析表明：不同入射角窄带调制方波脉冲激励下，场增强区域大小与微波通过窗户和门能直接照射到的区域大小呈正比，窗户的大小对建筑物内空间场强增强区域的大小有显著影响；同时在微波脉冲的传播方向上，窗沿后的区域场强幅值明显减小；脉冲宽度对建筑物内空间场强增强区域的大小及空间场强最大值影响很小；无上升下降沿的窄带调制方波脉冲激励下，空间电场叠加增强效应更强。测量了微波脉冲辐照下，建筑物内空间功率密度分布，验证了仿真结果。

| Abstract: | The paper conducts the 3D simulation of microwave pulses propagating,reflecting and transmitting in a building,to analyze the distribution of the maximum value of electric field in time domain.For narrow-band modulated square pulses with different incident angles,the size of field enhancement region is in direct proportion to the size of region irradiated by microwaves directly through the windows and doors,and the size of windows exerts great influence upon the the size of field enhancement region.The fiel... |
