| 摘 要： | 采用时域有限差分（FDTD）和离散傅里叶变换（DFFT）相结合的方法计算了不同长度及不同张角TEM喇叭接收天线的传递函数及灵敏度，采用最大相对误差和相对平均偏差分析了TEM喇叭超宽带接收的波形保真性与其几何尺寸之间的关系。分析结果表明：在设计高灵敏度及高波形保真性的超宽带TEM喇叭脉冲测量天线时，对TEM喇叭的张角和长度应进行折衷考虑。

| Abstract: | In this paper,the finite-difference time-domain (FDTD) and the discrete fast Fourier transform (DFFT) methods are adopted to calculate the transfer function and the sensitivity of TEM horn of various length and flare angle. The max relative error and the relative average deviation are used to analyze the ultra-wideband receiving characteristics. The results provide a basis to design a ultra-wideband receiving TEM horn. |
