摘要 理论上推导了均匀平面波垂直入射与任意入射时的透射系数,利用Fourier变换对各种超宽带(UWB)脉冲波形在室内墙体透射中的失真问题进行了研究,仿真结果和时域的精确结果对比,一致性良好,另外初步分析了波形失真的特性。 The refraction coefficient of wall has been deduced when the incidence angle of the uniform wave change verticle or arbitrary. Based on Fourier transformation, Various UWB pulse waveform distortion with indoor refraction is studied in this paper. Acomparison of Fourier transformation results with time-domain accurate results shows good agreements. Moreover, Properties of pulse waveform distortion were analyzed.
