摘　　要：给出了发射信号的脉冲参数,根据时域平面波理论得到了相应的远场特性计算公式,并结合实际要求给出了脉冲天线近场测量系统的配置方案.最后根据实测数据分析了脉冲天线近场测量中要注意的一些问题.The pulsed antenna near-field measurement technique is a novel antenna measurement technique developed since the 1990's. Pulse parameters of the transmitted signal are presented in this paper. With the plane-wave theory of time-domain fields, computing formulas of the far-field pattern are obtained. A setup scheme of the pulsed antenna near-field measurement system adaptable to practical requirements is given. Finally, some questions that ought to be paid attention to in pulsed antenna near-field measurement is analyzed on the basis of measured near-field data.
